13. Brake system

On cars the working brake system with the hydraulic drive is used.
The system works as follows:

– the pedal of a brake is connected with the main brake cylinder;
– when the pedal is pressed, liquid under pressure from the main brake cylinder on metal tubes and flexible hoses is transferred to lobbies and back brake mechanisms;
– working brake cylinders represent hydraulic modulators which transform the liquid pressure created in the main brake cylinder to movement of elements of the brake mechanism;
– forward and back pistons of a support of a brake move and due to friction about brake disks and drums provide the required delay of the car;
– at a brake pedal otpuskaniye pressure in system decreases. Brake shoes and pistons come back to a neutral or starting position and braking stops.

At reduction of level of brake fluid the liquid level sensor in the main brake cylinder includes a control lamp in combinations of devices. If the control lamp burns, first of all, check that the parking brake is released as the lamp indicates the lowered level of liquid and the tightened parking brake.
