3rd brake light mot failure

Deplete the stored vacuum by repeatedly applying the service brake. Brake efforts achieved during a test should be entered on the MOT testing service as follows: Enter the brake effort from each wheel and whether they ‘lock-up’. the car will pass an mot with the 2 required brake lights functioning, the 3rd brakelight is an extra and is not required as it is not a required brake light. There are two separate switches which form the breake light switch. Before carrying out a decelerometer test on the public highway, testers must ensure they are suitably qualified to drive the vehicle and are familiar with the controls. Completely empty the reservoir by repeatedly pressing the service brake pedal. Guidance for assessing corrosion and use of the corrosion assessment tool can be found in Appendix A. Vehicles of unknown test weight can be tested on either an RBT or plate brake tester (PBT). Technically, the third brake light must be tested. It is not necessary to drive the vehicle to carry out this inspection. Brake light. Vehicles first used before 1 October 1937 do not need to be tested for air and vacuum systems. ... Top 10 causes of MOT failure in the UK. As soon as the wheels are on the plate’s high friction braking surfaces, gradually apply the parking brake, keeping any “hold-on” button or trigger disengaged the whole time, until maximum effort is achieved. On the first run, just before the wheels are on the plate high friction surfaces, apply a light constant pressure to the brake pedal. (a) Endurance braking system connectors or mountings: (b) Endurance braking system obviously defective. well here is a solution to that problem. 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. Release the service brake and note if the vehicle is held on the gradient. 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. Record the reading at which the maximum braking effort is achieved and whether the wheels locked. Drive the vehicle on a level road at a steady speed of approximately 20mph (32kph) and progressively apply the secondary brake to maximum. You can change your cookie settings at any time. The brake force used in the efficiency calculation is the total from all wheels when operated by that control only. Will my motorhome fail an MOT with the high level brake light not working? Continue to apply the brake until maximum effort is achieved, or until the wheels lock and slip on the rollers. Click to expand... Hi there, The EPC light indicates if there is a problem with the breaks. just to be safe I would take it off for the MOT...put it in a bin and then blow up the bin!! Often a vehicle is fitted with an aftermarket brake pedal rubber. Three-wheeled vehicles only require a parking brake on one wheel. All other vehicles must achieve a minimum parking brake efficiency of 16%. Don’t worry we won’t send you spam or share your email address with anyone. However, if the number of wheel locks are not achieved for any system on a non-ATL RBT, a decelerometer test must be used to establish the overall brake efficiency of the relevant system(s). Drivers who ignore dashboard warning lights face MoT failure or costly repairs from today. Page generated in 0.253 seconds (26 queries), Currently Active Users Viewing This Thread: 1. Do not stop on the tester. Check the time it takes for the warning device to stop operating. 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. We aim to cater for a wider range of tastes here from Hot Rods & Street Rods all the way through to Bikes and Trucks . The secondary brake control may be the parking brake lever, or a separate brake control. If it too is not working, the brake-light switch, a … Stop the rollers if they have not stopped automatically. Enter the brake effort from each wheel. 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. Will A Cracked Tail Light Fail An Mot -> DOWNLOAD (Mirror #1) 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 … You only need to inspect vehicles that have not already had the parking brake system tested as the secondary brake. The over-centre lever type can be brake tested as normal using one of the approved test methods. Service brake pedal or hand lever condition and travel, 1.1.10. If the MOT testing service is unavailable, refer to the latest edition of the MOT Testing Guide. If the ABS has been intentionally rendered inoperative, the whole system must be removed.

(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. 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 981 posts. Apparently it's an MOT failure to have a non functioning high level brake light. Mine has stopped working and I cannot find out why. I would recommend getting the bulb/wiring of the third brake light fixed. Note whether the vehicle or steering pulls severely one way and the brake efficiency recorded. 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 However, they must have a parking brake that can prevent at least two wheels from turning. LandyZone - Land Rover Forum. Hydraulic parking brakes as an only means of operation are not acceptable on vehicles first used on or after 1 January 1968. I subscribed to ALLDATA.COM and found some better wiring schematics. Electronic parking brakes must be maintained in operation by direct mechanical means, even though they are applied electronically. Additional braking devices, such as electronic retarders, should not be operated during the brake test. It is not a defect unless the warning light stays on after the engine has been started. 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. I have failed them if less than 50% of the light source works. Being worn below the manufacturer’s recommended limits is not a reason in itself. Re: Covering 3rd brake light fails an MOT? For Class 7 vehicles, the brake efficiency will be calculated using one of the following: Enter the appropriate data to conduct the test. Drive the vehicle on a level road at a steady speed of approximately 20mph (32kph) and progressively apply the parking brake to maximum. A vehicle should only be failed for insufficient reserve if the pedal or lever is touching the floor/handlebar. So we have these possibilities: 1) A fuse somewhere 2) The brake switch on the pedal 3) This cruise control cell 4) Bad wiring Take note of the way the brake efforts fluctuate. 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. 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. Also if there are say 6 bulbs that make up the entire light strip and 4 … Service brake pedal or hand lever pivot, 1.1.2. A brake pedal rubber is an anti-slip material and is therefore not regarded as a defect if it’s worn smooth. 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. did you buy a aftermarket 3rd brake light and when you plug it in it stays lite up.

In these circumstances, the vehicle should be treated as having an unknown test weight. 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. (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. Yes, that is an MOT failure. 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. For Class 5 use the lesser of the DGW or maximum authorised mass (MAM) from the manufacturer’s plate. 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 … If both rollers are run together, it will almost certainly be necessary to chock the wheels that are not being tested. 2006 avalon 3rd brake light after mkt replace I decide not to pay the dealer $300-400 to replace my 3rd brake light. 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. Hold the vehicle on the service brake whilst setting the parking brake. In such cases the extent of reserve travel should be assessed during the brake test. For each check, drive the vehicle forwards at a steady speed of about 4mph up to the plate tester. You should only fail a vehicle if you can clearly see that the fluid is contaminated. You should reject a brake pedal if its grooves or raised grip sections are worn smooth. 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. 2.12 Tyres and wheels. safety, I've not heard of a brake light fitted for cosmetic reasons Tim. 40 replies 13.5K views aliadds Forumite. 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. If the parking brake is the ‘P’ position on the gearbox, the efficiency of the brake cannot be tested. 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. If you are not sure whether the pipe is sufficiently deteriorated to justify rejection, you should give the benefit of the doubt. When testing transmission parking brakes, the minimum parking brake efficiency requirement must be calculated before the brake is tested. Large vehicles fitted with spring brakes, lock actuators or air assisted parking brakes may require an applied brake test for assessing parking brake efficiency. component damaged or corroded: (c) Any component insecure or inadequately mounted. Record the reading at which the maximum braking effort is achieved and whether brake “lock-up” occurs. Service brake pedal or hand lever condition and travel. A brake pedal rubber is an anti-slip material and is therefore not regarded as a defect if it’s worn smooth. If the secondary brake is also the park brake then there is no need to carry out a separate park brake test. ... A ‘light source’ means any bulb, LED or other means of emitting light. You could fail your MOT for simply forgetting to replace faulty light bulbs on your motor. You may have to register before you can post: click the register link above to proceed.

Other pads may have a cut, which if worn away indicates that the pad must be replaced. Ensure that the vehicle, or system, under test is suitable for testing using a roller brake tester. For details of entering brake test results see Section 1.2.2. Some vehicles with full power hydraulic braking systems will illuminate the low-pressure warning light as soon as the ignition is switched on. Its not the ABS/traction/hand brake control light that's lit-just the pad light Is this now an MOT failure??? The MOT testing service will automatically pass or fail the vehicle on brake efficiency. However, they may be used to assist the application or release of a mechanical brake. Place the wheels of the next axle in the brake rollers and repeat the above procedure. Brake lights will not come on. 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. heynonnynonny Forumite. The service brake may be used to assist in setting the parking brake. 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: Start each brake roller in turn and note the recorded maximum effort. These will be inspected to check for: condition You should reject a hose for being excessively damaged or chafed only if it’s severe enough to expose the reinforcement. 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. 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. A gradient tester can be used on vehicles that are not suitable for a parking brake test with the primary brake tester or decelerometer. 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. A particular public road should not be used for tests so frequently that it could cause complaints from residents. A brake disc or drum must be significantly worn before you should reject it. However, the mechanism for keeping the brakes applied is usually within brake calliper or motor gear assembly and therefore not easy to see. The question is drivers are now placing stickers which obscure (not block) the HLBL. If a vehicle fails any aspect of the plate brake test, the check should be repeated to confirm the result. 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. It may be possible on motorcycle derived systems for the brake lever to touch the handlebar. 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. Stop the rollers if they have not stopped automatically. You must ensure that the vehicle is in a safe condition for the test to be carried out. For most vehicles the MOT testing service will calculate brake efficiencies automatically. 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 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. Unplug the brake-light switch and if the lights stay on, a short circuit is the case. For vehicle category definitions see the ‘Abbreviations and definitions’ in the ‘Introduction’. 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. 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. For details see Section 1.3.1 and 1.3.2. For the majority of vehicles, the MOT testing service will calculate brake imbalance automatically. It shows there to be a "cruise control cell" right before it branches off into the third brake light. You are currently viewing the FIAT Forum as a guest which gives you limited access to our many features. Tough Europe-wide test standards come into force to catch up with the rise of in-car electronics. (a) Other braking system (e.g. 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. The third brake light is normally centered and placed higher than the two typical brake lights below that flank the vehicle. 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. This test must only be conducted on an approved Class 5 roller brake tester with the appropriate ‘Applied Brake Test’ programme. A parking brake lever must have obvious excessive travel before being rejected. Start the engine and run it at just below the governed speed if diesel, or at 2,000rpm if petrol. 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. For Classes 3 and 4 use the weight shown by the brake test equipment. It is not a defect if the design pattern of the brake pedal rubber is worn smooth. 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. When testing transmission parking brakes, the minimum secondary brake efficiency requirement must be calculated before the brake is tested. Note if the pedal can be felt to travel further. 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.
