Price is also important to consider, although it does not always guarantee quality. You should only buy what you can afford. Always have in mind that an expensive tester does not mean that it is the best in the market. You can find cheaper options that offer similar or even better efficiency. On the same note, you would not expect a cheaply priced brake fluid tester to give the most accurate results or reliable service. b) Time taken to build up air pressure/vacuum to safe working value not in accordance with the requirements

For the majority of vehicles, the MOT testing service will calculate brake imbalance automatically. 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: 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. Testers should be aware of this throughout the test.

Ensure that the vehicle, or system, under test is suitable for testing using a roller brake tester. If the vehicle or system is unsuitable, it should be tested with a decelerometer. ATL test procedure For Class 5 use the lesser of the DGW or maximum authorised mass (MAM) from the manufacturer’s plate. 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:

Using a Brake Fluid Tester

Apply the parking brake fully and then release any power assistance. The service brake may be used to assist in setting the parking brake. For Class 5 use the lesser of the DGW or maximum authorised mass (MAM) from the manufacturer’s plate. On vehicles where only the ULW is displayed, you must calculate the DGW by multiplying the number of passenger seats by 63.5kg and adding the ULW, for example: 52 seats × 63.5kg = 3302kg + 5,250kg ULW = 8552kg. Prior to bleeding the system, conduct a master cylinder leak pass test. This is done by attaching a pressure gauge to the closest caliper brake pipe.

The primary brake tester must be used unless the vehicle is unsuitable due to its drive configuration, transmission type or braking system. If this is the case, a full or partial decelerometer test may be appropriate. You should consider any additional information from the vehicle manufacturer. 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.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.

i) the braking effort from any wheel is less than 70% of the maximum effort recorded from the other wheel on the same axle. Or in the case of testing on the road, the vehicle deviates excessively from a straight line 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. Brake fluid gradually absorbs moisture due to its hygroscopic nature. A brake fluid tester measures the ratio of moisture content in a vehicle’s brake fluid. It gives accurate results in seconds and thus allows the reader to identify the cars that need a change of brake fluid. All vehicles with a secondary brake control - in addition to or in place of the normal parking brake lever - must be inspected. Defect The primary brake tester must be used unless the vehicle is unsuitable due to its drive configuration, transmission type or braking system. If this is the case, a decelerometer or gradient test may be appropriate. A gradient test must only be carried out if the parking brake cannot be tested using the primary brake tester or decelerometer. This will usually only be necessary on certain all-wheel drive vehicles with electronic parking brakes where no vehicle technical information is available.Power up the tester, and the green light turns on automatically. Select the mode for the type of brake fluid you are using, and then remove the protective cap from the pen. Remove the caps and dip the probes into the brake fluid and watch the reading. The readings are usually from 0-4%, with 4 being the highest percentage, which necessitates a fluid change. 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. With the rollers still running, note whether a significant brake effort is recorded from any wheel without a brake being applied.
