4.3.21. Check of overall performance of the brake system

It is desirable to check overall performance of the brake system at special brake stands (similar to the applied traffic polices when carrying out technical inspection of cars) as the car is equipped with the anti-blocking system which is not allowing to bring braking to a skid of wheels (before receiving accurate traces of a brake way on asphalt). As a last resort approximate complex evaluation of the work of the brake system can be executed on the flat horizontal platform closed for traffic.
Accelerate the car without loading (in salon only the driver) on the I transfers to speed about 15 km/h. Sharply press a pedal of a brake and do not release it to a full stop of the car.
If when braking there was a car drift, go out of the car and examine the marks left by wheels. The brake trace of a serviceable wheel of the car with anti-blocking system is very small and almost imperceptible as the wheel does not slide, and slides on the verge of failure in a skid.
If at any wheel the brake track of the L of its blocking is covered accurately up, address to car service: the anti-blocking system is faulty.
If brake traces of all wheels are visible, but are hardly noticeable (there are no accurate marks left by the sliding tire) and length of all traces at the left and on the right is identical, the brake system is serviceable. Otherwise repair system.
