I subscribed to ALLDATA.COM and found some better wiring schematics. 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. A brake fluid warning lamp may be shared with other components, for example to indicate that brake pads are worn or the parking brake is applied. For each check, drive the vehicle forwards at a steady speed of about 4mph up to the plate tester. Brake servo units and master cylinder (hydraulic systems), 1.1.15. 1.1.2. 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. So what are you waiting for? A particular public road should not be used for tests so frequently that it could cause complaints from residents. on a mid 90s bmw 3 series my mate had most of the bulbs in the spoiler brake light go, and the MOT station told him leave it connected and it will fail, disconnect it and it will. Vehicles first used on 1 October 1937 or later must have their air and air/hydraulic braking systems inspected. Brake light. Note whether the vehicle or steering pulls severely one way and the brake efficiency recorded. Note the way in which the brake efforts increase and the maximum values achieved. You should reject a brake pedal if its grooves or raised grip sections are worn smooth. You should reject a hose for being excessively damaged or chafed only if it’s severe enough to expose the reinforcement. To start viewing messages, select the forum that you want to visit from the selection below. It must be done with care so that any protective coating does not get damaged. (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? For details of entering brake test results, see Section 1.2.2. It may be possible on motorcycle derived systems for the brake lever to touch the handlebar. However, they may be used to assist the application or release of a mechanical brake. 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. MOT Test of Brakes (1) Efficiency and balance of brakes is usually checked on a roller brake tester. There are two separate switches which form the breake light switch. M2 and M3 vehicles that were first used before 1 January 1968 and that have a service brake operating on at least 4 wheels, have no specified parking brake efficiency requirement. 3rd brake light LED not failure; If this is your first visit, be sure to check out the FAQ by clicking the link above. 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. A brake disc or drum must be significantly worn before you should reject it. Will A Cracked Tail Light Fail An Mot -> DOWNLOAD (Mirror #1) Continue to apply the parking brake until maximum effort is achieved, or until the wheels lock and slip on the rollers. It’s not permissible to remove or disable the ABS from a vehicle first used on or after 1 January 2010. 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. I have been having this problem for a long time now. Some defects in this sub-section may not apply to the type of parking brake fitted. Brake lights will not come on. 9 February 2010 at 10:29PM. The brake force used in the efficiency calculation is the total from all wheels when operated by that control only. well here is a solution to that problem. It's not an MOT failure to not have a high level brake light so perhaps best to remove if it's not working. For vehicle category definitions see ‘Abbreviations and definitions’ in the ‘Introduction’. If the ABS has been intentionally rendered inoperative, the whole system must be removed. The question is drivers are now placing stickers which obscure (not block) the HLBL. Apparently it's an MOT failure to have a non functioning high level brake light. One of the less common MOT failure reason is when an indicator flashes less than 60 times a minute. You should only fail a vehicle if you can clearly see that the fluid is contaminated. In these circumstances, the vehicle should be treated as having an unknown test weight. Other reasons why vehicles have failed their MOT is because the brake light appears even after the brake is … The legal requirement for MOTs is that, where a vehicle requires an MOT, a pass certificate must have been issued within the last 12 months (with leeway given for early presentation) so yes, it will still show as having a valid MOT until the expiry of the existing MOT … ... A ‘light source’ means any bulb, LED or other means of emitting light. LandyZone - Land Rover Forum. 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, does not need to be fitted with a warning device. Hope that helps. (a) Low-pressure warning gauge or indicator: (a) Control cracked, damaged or excessively worn, (b) Control insecure on valve or valve insecure, (c) Loose connections or leaks in the system. In such cases the extent of reserve travel should be assessed during the brake test. 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. 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. M1 vehicles having a service brake operating on at least 4 wheels and which were first used: M2 and M3 vehicles having a service brake operating on at least 4 wheels which were first used: L2 and L6 vehicles with a single service brake control that operates the brakes on all wheels. The MILs or dashboard warning lights will also be checked for the ABS, ESC, electronic park brake and brake fluid warning lights. As soon as the minimum efficiency requirement is reached the brake testing must cease to avoid any possible damage. You can get an MOT up to a month (minus a day) before it runs out and keep the same renewal date. Tough Europe-wide test standards come into force to catch up with the rise of in-car electronics. Brake cables, rods, levers and linkages, 1.1.16. Service brake pedal or hand lever condition and travel, 1.1.10. Gradually release the service brake and observe how the braking effort at each wheel reduces. Record the reading at which the maximum braking effort is achieved and whether the wheels locked. Registration is fast (less than 2 minutes), simple, absolutely free and gives you access to a wealth of FIAT information. Gradually apply the service brake and watch how the braking effort for each wheel increases. The third brake light is normally centered and placed higher than the two typical brake lights below that flank the vehicle. In such cases a gradient test must be carried out. 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 In such cases the test should be repeated in manual mode, running each roller individually. You’ve accepted all cookies. I have failed them if less than 50% of the light source works. For the majority of vehicles, the MOT testing service will calculate brake imbalance automatically. antifreeze pump, air dryer etc.) Brake Warning Light-MOT Failure? It will take only 2 minutes to fill in. If both rollers are run together, it will almost certainly be necessary to chock the wheels that are not being tested. the masks also let in some light round the edge, heres a pic of mine. Click to expand... Hi there, The EPC light indicates if there is a problem with the breaks. If the parking brake is the ‘P’ position on the gearbox, the efficiency of the brake cannot be tested. It is not necessary to drive the vehicle to carry out this inspection. My motorhome has a normal pair of brake lights by the indicators and a pair of brake lights on the motorcycle carrier. 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. Fully apply the brake and hold at a constant pressure. Technically, the third brake light must be tested. Take note of the way the brake efforts increase and the maximum values achieved. Vehicles first used before 1 October 1937 do not need to be tested for air and vacuum systems. Record the reading at which the maximum braking effort is achieved and whether brake “lock-up” occurs. Run the rollers on each axle that has the parking brake fitted and gradually apply the parking brake, keeping any ‘hold-on’ button or trigger disengaged the whole time. If the MOT testing service is unavailable, refer to the latest edition of the MOT Testing Guide. (a) Other braking system (e.g. If a vehicle fails any aspect of the plate brake test, the check should be repeated to confirm the result. 0. Guidance for assessing corrosion and use of the corrosion assessment tool can be found in Appendix A. 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. An MOT failure does not invalidate a previous MOT. ... Top 10 causes of MOT failure in the UK. 2.12 Tyres and wheels. Otherwise, take the weight from a weight data chart or some other reliable source. This can cause the ABS system to indicate a fault which may require specialist equipment to rectify. Often a vehicle is fitted with an aftermarket brake pedal rubber. Decelerometer brake testing must always be carried out on suitable roads with as little traffic as possible. We’ll send you a link to a feedback form. Hydraulic parking brakes as an only means of operation are not acceptable on vehicles first used on or after 1 January 1968. A brake pedal rubber is an anti-slip material and is therefore not regarded as a defect if it’s worn smooth. 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. 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 … These will be inspected to check for: condition We use cookies to collect information about how you use GOV.UK. Drive the vehicle forwards at a steady speed of about 4mph up to the plate tester. (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. just to be safe I would take it off for the MOT...put it in a bin and then blow up the bin!! Its not the ABS/traction/hand brake control light that's lit-just the pad light Is this now an MOT failure??? Unplug the brake-light switch and if the lights stay on, a short circuit is the case. Do not stop on the tester. This does not apply to sensor rings or other ABS components which are an integral part of another component, such as a brake disc or drive shaft. 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. You only need to inspect vehicles that have not already had the parking brake system tested as the secondary brake. Checks on vehicles with power-assisted braking systems should be carried out with the engine off. Warning devices may be visual or audible but only one needs to work if both are fitted. Also if there are say 6 bulbs that make up the entire light strip and 4 … Stop the rollers if they have not stopped automatically. For most vehicles the MOT testing service will calculate brake efficiencies automatically. On many vehicles, you will not be able to see if the brake fluid is contaminated. Hydraulic brake fluid level checks are confined to transparent reservoirs or where an indicator is fitted. Release the service brake and note if the vehicle is held on the gradient. Vehicles first used before 1 January 1915 only need one efficient braking system. We use this information to make the website work as well as possible and improve government services. Vehicles with a single line braking system must meet the following minimum secondary brake efficiency requirements: Vehicles first used before 1 January 1915 must only have one efficient braking system. with various words, ranging from a racing name to some rather unpleasant text. (a) Endurance braking system connectors or mountings: (b) Endurance braking system obviously defective. When testing transmission parking brakes, the minimum secondary brake efficiency requirement must be calculated before the brake is tested. 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’. For details of entering brake test results see Section 1.2.2. For details see Section 1.3.1 and 1.3.2. It shows there to be a "cruise control cell" right before it branches off into the third brake light. If you are not sure whether the pipe is sufficiently deteriorated to justify rejection, you should give the benefit of the doubt. For vehicle category definitions see the ‘Abbreviations and definitions’ in the ‘Introduction’. The over-centre lever type can be brake tested as normal using one of the approved test methods. We aim to cater for a wider range of tastes here from Hot Rods & Street Rods all the way through to Bikes and Trucks . Enter the brake effort from each wheel. 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. 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“. For vehicles other than Class 7, establish the actual presented weight of the vehicle. Large vehicles fitted with spring brakes, lock actuators or air assisted parking brakes may require an applied brake test for assessing parking brake efficiency. Re: Covering 3rd brake light fails an MOT? Three-wheeled vehicles only require a parking brake on one wheel. For Classes 3 and 4 use the weight shown by the brake test equipment. 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. A vehicle should only be failed for insufficient reserve if the pedal or lever is touching the floor/handlebar. You could fail your MOT for simply forgetting to replace faulty light bulbs on your motor. If the vehicle or system cannot be tested on a roller brake tester, set up the decelerometer in the vehicle in accordance with the equipment manufacturer’s instructions. 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. Is the high level braking light part of the MoT test? However, some vehicles may have been manufactured with a brake pedal which did not incorporate grooves or the fitting of an anti-slip material and these should not be rejected. Place the wheels of the next axle in the brake rollers and repeat the above procedure. Start the engine and run it at just below the governed speed if diesel, or at 2,000rpm if petrol. 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. 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.
