Checking the effectiveness of the brake system

It is advisable to check the efficiency of the brake system on special brake stands (similar to those used in the technical inspection of vehicles). In extreme cases, an approximate comprehensive assessment of the operation of the brake system can be performed on a flat horizontal area, closed to traffic.

Car without load (in the cabin only the driver) accelerate to a speed of approximately 15-20 km / h. Depress the brake pedal sharply to obtain the maximum possible deceleration and do not release it until the vehicle has come to a complete stop.

If the car stopped without deviating from a straight line, and the deceleration was sufficiently intense, the braking system can be considered serviceable. Otherwise, check the condition of the elements and repair the system if necessary.

Note: The following ratios must be observed (pic. 9.5):

• L_{lion. per.} = L_{is right. per.}
• L_{lion. rear} = L is right. rear
• L_trans. > L_rear

Warnings: If a similar test on an ABS-equipped vehicle shows brake marks as clear as a test on a non-ABS vehicle, then the anti-lock brake system is faulty. In this case, immediately contact a car service for its repair. Do not abuse this assessment, because it is associated with increased one-sided tire wear.
