Testers should be aware of this throughout the test. 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. A parking brake lever must have obvious excessive travel before being rejected. It may be possible on motorcycle derived systems for the brake lever to touch the handlebar. Some vehicles with full power hydraulic braking systems will illuminate the low-pressure warning light as soon as the ignition is switched on. The service brake may be used to assist in setting the parking brake. (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? I have been having this problem for a long time now. Additional braking devices, such as electronic retarders, should not be operated during the brake test. When testing transmission parking brakes, the minimum parking brake efficiency requirement must be calculated before the brake is tested. 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. Technically, the third brake light must be tested. Don’t worry we won’t send you spam or share your email address with anyone. 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. Drive the vehicle forwards at a steady speed of about 4mph up to the plate tester. Mine has stopped working and I cannot find out why. It will take only 2 minutes to fill in. You are permitted to use an alternative procedure to that specified below as long as all the testable elements are adequately covered. Release the service brake and note if the vehicle is held on the gradient. Take note of the way the brake efforts fluctuate. 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. To help us improve GOV.UK, we’d like to know more about your visit today. (c) Brake hoses or connections leaking on: (b) Brake lining or pad contaminated with oil, grease etc. Instead I ordered a 3rd party light, $30 with shipping, and took an hour to replace it. with various words, ranging from a racing name to some rather unpleasant text. In such cases the test should be repeated in manual mode, running each roller individually. For each check, drive the vehicle forwards at a steady speed of about 4mph up to the plate tester. In such cases a gradient test must be carried out. Registration is fast (less than 2 minutes), simple, absolutely free and gives you access to a wealth of FIAT information. Also if there are say 6 bulbs that make up the entire light strip and 4 … If the secondary brake is also the park brake then there is no need to carry out a separate park brake test. You should take into account any additional information from the vehicle manufacturer. Forums > Land Rover Forums > Land Rover Discovery > This site uses cookies. The over-centre lever type can be brake tested as normal using one of the approved test methods. For details of entering brake test results see Section 1.2.2. Warning devices may be visual or audible but only one needs to work if both are fitted. LandyZone - Land Rover Forum. 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. We aim to cater for a wider range of tastes here from Hot Rods & Street Rods all the way through to Bikes and Trucks . 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. All content is available under the Open Government Licence v3.0, except where otherwise stated, 1.1.1. Some defects in this sub-section may not apply to the type of parking brake fitted. On vehicles where only the ULW is displayed, you must calculate the DGW by multiplying the number of passenger seats by 63.5kg (or 140lbs) and adding the ULW, for example: Brake Warning Light-MOT Failure? 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. However, if the rollers are run together and the vehicle fails to meet the minimum performance requirement, the test must be repeated running the rollers individually. When checking maximum effort, testers can elect to run the brake rollers individually or together, depending on the suitability of the RBT. With the rollers still running, note whether a significant brake effort is recorded from any wheel without a brake being applied. For Class 7 vehicles, the brake efficiency will be calculated using one of the following: Enter the appropriate data to conduct the test. Will A Cracked Tail Light Fail An Mot -> DOWNLOAD (Mirror #1) Ensure that the vehicle, or system, under test is suitable for testing using a roller brake tester. 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. It is not a defect unless the warning light stays on after the engine has been started. Finding such a shorted-circuit, is best left to a professional. If the parking brake is the ‘P’ position on the gearbox, the efficiency of the brake cannot be tested. 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). When the brake lights will not come on, the first thing to check is the third-brake light. 1.1.2. You must check the strength and continuity of the vehicle’s load bearing members and their supporting structure or panelling around any braking component mounting. 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. The MOT is a simple test of roadworthiness, and is not to be confused with a vehicle health check.. You can get an MOT up to a month (minus a day) before it runs out and keep the same renewal date. We’ll send you a link to a feedback form. (a) Other braking system (e.g. (c) Actuator insecure or inadequately mounted and: (b) Load sensing valve linkage obviously incorrectly adjusted. It also has a high level brake light up by the roof which has stopped working due to water ingress. Fully apply the brake and hold at a constant pressure. Apparently it's an MOT failure to have a non functioning high level brake light. Record the reading at which the maximum braking effort is achieved and whether brake “lock-up” occurs. Gradually depress the service brake again, this time until maximum effort is achieved, or until the wheel locks and slips on the rollers. You should only fail a vehicle if you can clearly see that the fluid is contaminated. As soon as the minimum efficiency requirement is reached the brake testing must cease to avoid any possible damage. (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. For vehicle category definitions see the ‘Abbreviations and definitions’ in the ‘Introduction’. 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’. 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. The MILs or dashboard warning lights will also be checked for the ABS, ESC, electronic park brake and brake fluid warning lights. For the majority of vehicles, the MOT testing service will calculate brake imbalance automatically. When testing ABS equipped vehicles, the road wheels that are lifted off the ground should not be allowed to rotate when the ignition is on. 9 February 2010 at 10:29PM. A brake pedal rubber is an anti-slip material and is therefore not regarded as a defect if it’s worn smooth. I have read somewhere that if it is fitted it must work. 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 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. 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. So what are you waiting for? However, the mechanism for keeping the brakes applied is usually within brake calliper or motor gear assembly and therefore not easy to see. This test must only be conducted on an approved Class 5 roller brake tester with the appropriate ‘Applied Brake Test’ programme. So we have these possibilities: 1) A fuse somewhere 2) The brake switch on the pedal 3) This cruise control cell 4) Bad wiring 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. 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. For details see Section 1.3.1 and 1.3.2. It's not an MOT failure to not have a high level brake light so perhaps best to remove if it's not working. 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. Deplete the stored vacuum by repeatedly applying the service brake. These will be inspected to check for: condition A small number of large vehicles, such as some American motor caravans, have a parking brake which is not suitable for a dynamic brake test. Vehicles first used before 1 October 1937 do not need to be tested for air and vacuum systems. (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. It shows there to be a "cruise control cell" right before it branches off into the third brake light. A vehicle should only be failed for insufficient reserve if the pedal or lever is touching the floor/handlebar. Its not the ABS/traction/hand brake control light that's lit-just the pad light Is this now an MOT failure??? Checks on vehicles with power-assisted braking systems should be carried out with the engine off. 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. 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. For vehicle category definitions see ‘Abbreviations and definitions’ in the ‘Introduction’. You should reject a hose for being excessively damaged or chafed only if it’s severe enough to expose the reinforcement. You may have to register before you can post: click the register link above to proceed. However, they may be used to assist the application or release of a mechanical brake. 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. All other vehicles must achieve a minimum parking brake efficiency of 16%. A brake pedal rubber is an anti-slip material and is therefore not regarded as a defect if it’s worn smooth. It is not necessary to drive the vehicle to carry out this inspection. ... Top 10 causes of MOT failure in the UK. Yes, that is an MOT failure. If your car was not fitted with the brake light then it could not have failed a good example of this is: The spare wheel has insufficent tread therefore it fails. 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. In such cases the extent of reserve travel should be assessed during the brake test. Enter the efficiencies recorded by the meter. Vehicles first used before 1 January 1915 only need one efficient braking system. 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. You only need to inspect vehicles that have not already had the parking brake system tested as the secondary brake. Some tricycles with two brake controls may have a linked braking system. For vehicles other than Class 7, establish the actual presented weight of the vehicle. 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.
