You’ve accepted all cookies. If the MOT testing service is unavailable, refer to the latest edition of the MOT Testing Guide. If it too is not working, the brake-light switch, a … For Class 7 use the DGW from the manufacture’s plate or, the nominal DGW of 2,600kg if using a plate brake tester and the presented weight is less than 2,000kg. A particular public road should not be used for tests so frequently that it could cause complaints from residents. The MOT is a simple test of roadworthiness, and is not to be confused with a vehicle health check.. (c) Brake hoses or connections leaking on: (b) Brake lining or pad contaminated with oil, grease etc. (a) Insufficient pressure/vacuum assistance for less than: (b) Time taken to build up air pressure/vacuum to safe working value not in accordance with the requirements, (c) Repeated operation of any ancillary air or vacuum system completely depletes the stored air or vacuum for the braking system, (d) Air leak causing a noticeable drop in pressure or audible air leak, (e) External damage likely to affect the function of the braking system. Really does nothing for the car! However, when this is not the case, such as for tricycles and quadricycles or if MTS is not working, you must calculate the brake imbalance against the maximum brake efforts on each axle in the following way: Disregard any brake imbalance across an axle if the lower recorded effort is as a result of a locked wheel or if the higher brake effort from a wheel is not more than 40kg. Its not the ABS/traction/hand brake control light that's lit-just the pad light Is this now an MOT failure??? You should only fail a vehicle if you can clearly see that the fluid is contaminated. Some brake pads have metal wear indicators so that when the pads become excessively worn the metal indicator touches the disc making a squealing sound. 52 seats × 63.5kg = 3302kg + 5,250kg ULW = 8552kg. The MILs or dashboard warning lights will also be checked for the ABS, ESC, electronic park brake and brake fluid warning lights. In these circumstances, the vehicle should be treated as having an unknown test weight. To help us improve GOV.UK, we’d like to know more about your visit today. Can you offer a little advise, whats is the current standing on High Level brake lights (HLBL) or also known as 3rd brake light, normally placed in the top middle of your rear window. Is the high level braking light part of the MoT test? The MOT testing service will automatically calculate brake efficiency and out of balance results. An endurance braking system, such as an exhaust brake or electronic retarder is only likely to be fitted to some large motor caravans and category M2 and M3 vehicles. Deplete the stored vacuum by repeatedly applying the service brake. For example, if your MOT was due to run out on 15 June, you would be able to book an MOT on 16 May and the MOT would last until 15 June the following year. On many vehicles, you will not be able to see if the brake fluid is contaminated. Do not stop on the tester. Instead I ordered a 3rd party light, $30 with shipping, and took an hour to replace it. If I remove it completely as long as the other brake lights are working will I get away with this? For vehicle category definitions see the ‘Abbreviations and definitions’ in the ‘Introduction’. For vehicles other than Class 7, establish the actual presented weight of the vehicle. You may have to register before you can post: click the register link above to proceed. 2006 avalon 3rd brake light after mkt replace I decide not to pay the dealer $300-400 to replace my 3rd brake light. Hydraulic parking brakes as an only means of operation are not acceptable on vehicles first used on or after 1 January 1968. They do not need to meet a specified efficiency requirement. The over-centre lever type can be brake tested as normal using one of the approved test methods. However, they may be used to assist the application or release of a mechanical brake. An electronic parking brake (EPB) may apply automatically in certain conditions, such as when the ignition is switched off or when the driver’s door is opened. It is not a defect if the design pattern of the brake pedal rubber is worn smooth. My motorhome has a normal pair of brake lights by the indicators and a pair of brake lights on the motorcycle carrier. As soon as the minimum efficiency requirement is reached the brake testing must cease to avoid any possible damage. Brake light. It is not a defect unless the warning light stays on after the engine has been started. Some defects in this sub-section may not apply to the type of parking brake fitted. One of the less common MOT failure reason is when an indicator flashes less than 60 times a minute. Enter the brake effort from each wheel. For each check, drive the vehicle forwards at a steady speed of about 4mph up to the plate tester. The question is drivers are now placing stickers which obscure (not block) the HLBL. Note the way in which the brake efforts increase and the maximum values achieved. 9 February 2010 at 10:29PM. I would recommend getting the bulb/wiring of the third brake light fixed. You must inspect the warning lamp operation on vehicles with an electronically controlled air braking system. Additional braking devices, such as electronic retarders, should not be operated during the brake test. In such cases the extent of reserve travel should be assessed during the brake test. If the vehicle or system is of a type which cannot be tested on a roller brake tester, set up the decelerometer in the vehicle in accordance with the equipment manufacturer’s instructions. These will be inspected to check for: condition Hold the vehicle on the service brake whilst setting the parking brake. Also if there are say 6 bulbs that make up the entire light strip and 4 … There are two separate switches which form the breake light switch. Checks on vehicles with power-assisted braking systems should be carried out with the engine off. Brake cables, rods, levers and linkages, 1.1.16. Guidance for assessing corrosion and use of the corrosion assessment tool can be found in Appendix A. Surfer – According to the Intro to this Conversation [also dated 2012] “The MOT test now includes a ‘Malfunction Indicator Lamp’ check.This requires the examiner to visually check that warning lights for electronic stability control, safety restraint systems, anti-lock braking systems and tyre pressure monitoring systems are not permanently illuminated“. Quadricycles may be fitted with one of the following types of parking brake: These machines are type approved and should not be rejected for design features that prevent them from meeting the stated requirements. just to be safe I would take it off for the MOT...put it in a bin and then blow up the bin!! If the primary brake tester is not suitable for the vehicle’s drive configuration, transmission type or braking system, a full or partial decelerometer test may be appropriate. L5 vehicles with a single service brake control that operates the brakes on all wheels which were first used: Vehicles first used before 1 January 1968 which do NOT have one means of control operating on at least 4 wheels and which have one brake system with two means of control or two brake systems with separate means of control, Any L category vehicle with two service brake systems each having a separate means of operation, Vehicles first used before 1 January 1915 only require one efficient braking system, M2 and M3 vehicles having a service brake operating on at least 4 wheels which were first used before 1 January 1968, (a) Parking brake inoperative on one side, or in the case of testing on the road, the vehicle deviates excessively from a straight line, (a) Control for electronic retarder does not allow gradual variation in effort, (b) Warning device shows system malfunction, (c) Wheel speed sensors missing or damaged, 45psi (3.1kg/cm2 or 3 bar) for a pressure gauge, 10” to 12” (25 to 30cm) for a vacuum gauge, an over-centre lever that is mounted on handlebars, a gear lever that operates a cable when it’s moved into the park position, a transmission lock, which is the ‘P’ position on machines with continuously variable transmission (CVT), the actual design gross weight (DGW) where the presented weight is at least 2,000kg (the DGW is obtained from the manufacturer’s plate fitted to the vehicle), a nominal DGW figure of 2,600kg if the presented weight is less than 2,000kg. It also has a high level brake light up by the roof which has stopped working due to water ingress. In such cases the test should be repeated in manual mode, running each roller individually. A brake pedal without a rubber usually has grooves or raised sections to provide grip in wet conditions and should be rejected if it’s worn smooth. (c) Brake lining or pad missing or incorrectly mounted, (b) Component excessively worn or corroded, (d) Cable guide defective affecting operation, (e) Restriction in free movement of the braking system, (f) Abnormal movement of levers indicating maladjustment or excessive wear. A vehicle should only be failed for insufficient reserve if the pedal or lever is touching the floor/handlebar. So what are you waiting for? Otherwise, take the weight from a weight data chart or some other reliable source. your car will pass an mot without this one working however make sure that both your bulbs work on the tail lights to meet legal requirements Drive the vehicle on a level road at a steady speed of approximately 20mph (32kph) and progressively apply the secondary brake to maximum. As soon as the minimum efficiency requirement is reached the brake testing must cease to avoid any possible damage. You should take into account any additional information from the vehicle manufacturer. Chafing, corrosion or damage to a rigid brake pipe so that its wall thickness is reduced by 1/3 (approximately 0.25mm for typical hydraulic brake pipe) justifies rejection, although it’s accepted that this is not easy to determine. Register now to join our community of over 125,000 members and gain instant access to all we have to offer. However, you should not reject a brake pedal if the vehicle has been manufactured with one that does not have grooves or anti-slip material. Some tricycles with two brake controls may have a linked braking system. In cases where the required brake efficiency is only just met, but the tester knows that a higher performance figure is normally obtained for the vehicle type, the vehicle presenter should be informed. For vehicle category definitions see ‘Abbreviations and definitions’ in the ‘Introduction’. (c) Load sensing valve seized or inoperative and: (d) Load sensing valve missing where fitted as standard, (a) Adjuster damaged, seized or having abnormal movement, excessive wear or incorrect adjustment. Mine has stopped working and I cannot find out why. Click to expand... Hi there, The EPC light indicates if there is a problem with the breaks. Certain converted passenger vehicles, such as motor caravans and ambulances, may have a kerb weight greatly in excess of the base model weight displayed by the MOT testing service. For Class 7 vehicles, the brake efficiency will be calculated using one of the following: Enter the appropriate data to conduct the test. Incorrect headlamp aim; ... brake, reverse and fog lights work. If the vehicle or system cannot be tested on a roller brake tester, set up the decelerometer in the vehicle as instructed by the equipment manufacturer. Fully apply the brake and hold at a constant pressure. When the brake lights will not come on, the first thing to check is the third-brake light. The car passed MOT despite the EPC light being on. With the rollers still running, note whether a significant brake effort is recorded from any wheel without a brake being applied. You should reject a hose for being excessively damaged or chafed only if it’s severe enough to expose the reinforcement. Don’t worry we won’t send you spam or share your email address with anyone. Vehicles first used before 1 October 1937 do not need to be tested for air and vacuum systems. just a quick one I have always passed and advised if a high level brake light is not working (factory fit or after market) simply because I have no proof its a stop light. All vehicles with a secondary brake control - in addition to or in place of the normal parking brake lever - must be inspected. The secondary brake control may be the parking brake lever, or a separate brake control. Stop the rollers. It may be possible on motorcycle derived systems for the brake lever to touch the handlebar. Position the wheels of the first axle to be tested in the brake rollers and then run both sets of rollers together in a forward direction until the vehicle is aligned. 40 replies 13.5K views aliadds Forumite. my mate failed his MOT today on a couple of things one of which was his 3rd brake light not working, can they fail you for that? Testers should be aware of this throughout the test. (3rd brake light) What has happened is that one of the 6 sections has stopped working, but the others are fine (so you can essentially see a gap in the light when illuminated) Just wondering if anyone can tell me whether this is an MOT failure or not? Adding this third light captures the line of sight of the drivers following the car, as opposed to the use of just two lights, making the braking reaction faster. We use cookies to collect information about how you use GOV.UK. I have failed them if less than 50% of the light source works. It must be done with care so that any protective coating does not get damaged. Stopping short of lock up or maximum effort, hold a steady pedal pressure and check there is no excessive brake effort fluctuation with each revolution of the road wheel. Vehicles of unknown test weight can be tested on either an RBT or plate brake tester (PBT). An MOT failure does not invalidate a previous MOT. Drivers who ignore dashboard warning lights face MoT failure or costly repairs from today. Brake servo units and master cylinder (hydraulic systems), 1.1.15. Apparently it's an MOT failure to have a non functioning high level brake light. I have read somewhere that if it is fitted it must work. For details see Section 1.3.1 and 1.3.2. Brake condition and operation, service brakes, secondary brakes, parking brakes, anti-lock braking system (ABS), electronic braking system (EBS) and brake fluid rules and inspection for car and passenger vehicle MOT tests. Automated test lane (ATL) approved test stations should position the front wheels of the vehicle in the rollers of the brake tester and follow the sequence of instructions as displayed and prompted on screen. Record the reading at which the maximum braking effort is achieved and whether the wheels locked. I have been having this problem for a long time now. You can change your cookie settings at any time. If a vehicle is ejected from the brake rollers, the required brake efforts may not be achieved. As soon as the wheels are on the plate high friction braking surfaces, gradually apply the secondary brake, keeping any ‘hold-on’ button or trigger disengaged the whole time, until maximum effort is achieved. A vehicle with an ULW up to and including 3,050kg with a reservoir coupled direct to the induction manifold or a reservoir integral in a servo unit, is not necessarily required to be fitted with a warning device. Continue to apply the parking brake until maximum effort is achieved, or until the wheels lock and slip on the rollers. (d) Braking system component modification: (e) The strength or continuity of the load bearing structure within 30cm of any braking system actuation component mounting (a prescribed area): (b) Brakes imbalance across an axle such that: (c) A brake on any wheel grabbing severely, (d) Abnormal lag in brake operation on a wheel, (e) Excessive fluctuation in brake effort through each wheel revolution, (f) Significant brake effort recorded with no brake applied indicating a binding brake, (g) Brake performance unable to be tested. safety, I've not heard of a brake light fitted for cosmetic reasons Tim. Mot requirements are - any brake light/lamp fitted as standard or fitted and is known to be electrically connected must work and min 50% is visible. This test must only be conducted on an approved Class 5 roller brake tester with the appropriate ‘Applied Brake Test’ programme. Tough Europe-wide test standards come into force to catch up with the rise of in-car electronics. Hope that helps. Any good MOT tester finding a failed brake light bulb would issue a failed certificate (to ensure that DVLA recognise they are failing cars appropriately) and fit a bulb then issue a pass. It’s not permissible to remove or disable the ABS from a vehicle first used on or after 1 January 2010. Hydraulic brake fluid level checks are confined to transparent reservoirs, reservoir caps should not be removed. If MTS is not working, add the brake efforts from each wheel for the system that is being tested and carry out the following calculation: The vehicle test weight will depend on the vehicle test class. Is a Non working high level brake light a MOT failure Welcome to Rods 'n' Sods, the most active and friendly UK Rod and Custom website. TitanTim wrote: ↑ Wed Apr 17, 2019 7:03 am I would have thought if a third brake light is fitted it would fail the MOT if not working as it's fitted for a reason i.e. Any item on a car that has to be checked in accordance with MOT rules must be working or it will result in a failue point. - For more news, reviews and Top Tens, visit https://www.honestjohn.co.uk Join the largest FIAT community on the web today! If the ABS has been intentionally rendered inoperative, the whole system must be removed. If the metal brake pipes have surface dirt that needs to be removed before it’s possible to assess their condition, you can lightly scrape the pipe with a specialist brake pipe corrosion tool or the corrosion assessment tool ‘spade end’. But if the MoT tester is unsure if it's connected then they should give the car the benefit of the doubt and pass it. I subscribed to ALLDATA.COM and found some better wiring schematics. You only need to inspect vehicles that have not already had the parking brake system tested as the secondary brake. It is not necessary to drive the vehicle to carry out this inspection. In such cases a gradient test must be carried out. Wotan. The 540i/T has failed its MOT on some of the 3rd brake light bulbs not illuminating so I went to remove it and replace them/check for dry solders following these … Take note of the way the brake efforts increase and the maximum values achieved. Brake actuators - including spring brakes, hydraulic cylinders and callipers, 1.1.19. To start viewing messages, select the forum that you want to visit from the selection below. If a vehicle has special controls, such as in disability vehicles, the vehicle presenter should be allowed to drive during the test if he/she wishes. You must ensure that the vehicle is in a safe condition for the test to be carried out. You can get an MOT up to a month (minus a day) before it runs out and keep the same renewal date. So we have these possibilities: 1) A fuse somewhere 2) The brake switch on the pedal 3) This cruise control cell 4) Bad wiring Enter the efficiencies recorded by the meter. 0. If a vehicle fails any aspect of the plate brake test, the check should be repeated to confirm the result. These vehicles must instead meet the secondary brake test requirements. This inspection is only for vehicles with a single line braking system. It will take only 2 minutes to fill in. Hydraulic brake fluid level checks are confined to transparent reservoirs or where an indicator is fitted. Record the reading at which the maximum braking effort is achieved and whether brake “lock-up” occurs. On the first run, just before the wheels are on the plate high friction surfaces, apply a light constant pressure to the brake pedal. Alternatively, the efficiency requirements are met if the front wheels lock on the service brake of an unladen Class 7 vehicle with at least a 100kg force at each rear wheel for a two-axle vehicle, or at least 50kg force at each rear wheel on a three-axle vehicle. Decelerometer brake testing must always be carried out on suitable roads with as little traffic as possible. For most vehicles the MOT testing service will calculate brake efficiencies automatically. I'm going on the basis that its a warning sign rather than an actual fault,same as if your low washer fluid light is lit but still works fine, and I guess its an advisory rather than a fail For details of entering brake test results, see Section 1.2.2. For Classes 3 and 4 use the weight shown by the brake test equipment. heynonnynonny Forumite. All other vehicles must achieve a minimum parking brake efficiency of 16%. (a) Endurance braking system connectors or mountings: (b) Endurance braking system obviously defective. LandyZone - Land Rover Forum. On connecting the new brake light to the existing wiring, still no illumination although I have bench tested it and no problems with the unit itself. Apply the parking brake fully and then release any power assistance. Unplug the brake-light switch and if the lights stay on, a short circuit is the case. Stop the rollers if they have not stopped automatically. When testing transmission parking brakes, the minimum parking brake efficiency requirement must be calculated before the brake is tested. Start each brake roller in turn and note the recorded maximum effort. Registration is fast (less than 2 minutes), simple, absolutely free and gives you access to a wealth of FIAT information. In certain cases where a roller brake tester may not be used (for example on certain 4-wheel drive vehicles) it may be necessary to check brake efficiency and balance on a road test, with a portable decelerometer (pictured below). We’ll send you a link to a feedback form. MOT Test of Brakes (1) Efficiency and balance of brakes is usually checked on a roller brake tester. antifreeze pump, air dryer etc.) When conducting a test on a roller brake tester (RBT) where more than half of the wheels of a brake system lock the efficiency requirements for that system are considered to be met. Additional braking device (retarder), if fitted, ‘Abbreviations and definitions’ in the ‘Introduction’, Coronavirus (COVID-19): guidance and support, Check how the new Brexit rules affect you, Transparency and freedom of information releases, (c) Anti-slip provision missing, loose or worn smooth. We use this information to make the website work as well as possible and improve government services. Often a vehicle is fitted with an aftermarket brake pedal rubber. The third brake light is normally centered and placed higher than the two typical brake lights below that flank the vehicle. However, they must have a parking brake that can prevent at least two wheels from turning. Service brake pedal or hand lever condition and travel, 1.1.10. Place the wheels of the next axle in the brake rollers and repeat the above procedure. (b) Parking brake lever pivot or ratchet mechanism: (c) Parking brake lever has excessive movement indicating incorrect adjustment, (d) Parking brake control missing, defective or inoperative, (e) Electronic parking brake MIL indicates a malfunction, (f) Parking brake is not capable of being maintained in operation by direct mechanical action only (vehicle first used on or after 1 January 1968), (b) Excessive oil discharge from a compressor or brake valve, (c) Valve insecure or inadequately mounted, (c) Reservoir insecure or inadequately mounted, (e) Master cylinder reservoir cap missing, (f) Brake fluid warning light illuminated or defective, (g) Incorrect functioning of brake fluid level warning device, (a) Brake pipe is at imminent risk of failure or fracture, (c) Brake pipe damaged or excessively corroded, (a) Brake hose damaged and likely to fail. When checking maximum effort, testers can elect to run the brake rollers individually or together, depending on the suitability of the RBT. You are permitted to use an alternative procedure to that specified below as long as all the testable elements are adequately covered. Service brake pedal or hand lever pivot, 1.1.2. For details of conducting the test see Section 1.4.1. It's not an MOT failure to not have a high level brake light so perhaps best to remove if it's not working. Will my motorhome fail an MOT with the high level brake light not working? 3rd brake light LED not failure; If this is your first visit, be sure to check out the FAQ by clicking the link above. If this would result in failure for beam aim being too low, the Tester will re-check the beam aim with the control set at its ‘highest’ position. 981 posts. Gradually depress the service brake again, this time until maximum effort is achieved, or until the wheel locks and slips on the rollers. A brake pedal rubber is an anti-slip material and is therefore not regarded as a defect if it’s worn smooth. The rise of in-car electronics Light-MOT failure???????????.
