A brake pedal rubber is an anti-slip material and is therefore not regarded as a defect if it’s worn smooth. 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

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. Defect Some tricycles with two brake controls may have a linked braking system. The brake force used in the efficiency calculation is the total from all wheels when operated by that control only. Using a roller brake testerVehicles 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 Vehicles first used before 1 January 1915 only need one efficient braking system. They do not need to meet a specified efficiency requirement. 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. 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. Some brake fluid testers have better features than others that enable ease of use and more accurate results. For instance, one may have LED lights to show the corresponding percentage of water, while others show the percentage on a screen. One LED fluid tester pen may come with a free battery, while in others, you have to buy it separately. 4. Price Drive the vehicle on a level road at a steady speed of approximately 20mph (32kph) and progressively apply the secondary brake to maximum.

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.When testing transmission parking brakes, the minimum parking brake efficiency requirement must be calculated before the brake is tested. As soon as the minimum efficiency requirement is reached the brake testing must cease to avoid any possible damage. 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. In these circumstances, the vehicle should be treated as having an unknown test weight. Open the bonnet find the brake fluid reservoir. If you’re unsure where this is, refer to your vehicle manual. If the parking brake is the ‘P’ position on the gearbox, the efficiency of the brake cannot be tested. The tester must therefore assess the brake by using a gradient (ideally 16%), or by attempting to push the machine when ‘P’ is selected. Guidance for assessing corrosion and use of the corrosion assessment tool can be found in Appendix A. Defect
