On the car the system of the hydraulic booster of brakes is installed to carry out bigger brake effort if necessary to carry out the minimum effort when pressing a brake pedal.

The brake system can work with full efficiency even if the system of the hydraulic booster will not function. If the system of the hydraulic booster does not work, you should make bigger effort when pressing a brake pedal. In case the system of the hydraulic booster of brakes ceases to function on какойлибо to the reason (for example, repeated pressing a brake pedal at the switched-off engine), the brake system will continue to function.

Force with which it will be necessary to press a brake pedal for braking of the car will significantly increase in comparison with that which was required when the system of the hydraulic booster worked. If hydraulic brake system, any of two contours, fails, braking of the car can be carried out, only with smaller efficiency. The increased brake pedal course, need of stronger pressing a brake pedal for braking or a stop of the car and inclusion of an alarm bulb of the brake system will testify to an exit of one of contours of the brake system out of operation.

Prevention If the system of the hydraulic booster of brakes fails or if one of contours of the brake system fails, it is necessary to address immediately experts for check and repair of the brake system.
