general information For vehicles used by the service braking system with hydraulic drive. The system operates as follows: - The brake pedal is connected to the master cylinder;
- When the pedal is depressed, the pressurized fluid from the master cylinder by the metal tube and the flexible hose is transmitted to the front and rear brakes;
- The wheel cylinders are hydraulic modulators that convert the fluid pressure generated in the master cylinder, in the movement of the elements of the brake mechanism;
- Front and rear brake caliper pistons and move due to friction on the brake discs and drums provide the required vehicle deceleration;
- When you release the brake pedal pressure in the system decreases.
Brake pads and the pistons return to a neutral or home position and deceleration stops. By reducing the brake fluid level sensor liquid level in the master cylinder includes a warning lamp in the instrument cluster. If the warning lamp lights up in the first place, check that the parking brake is released, as the lamp is indicating a reduced level of the liquid and apply the parking brake.
