- 1. Expansion tank on the master brake cylinder: serves to store the working fluid of the hydraulic brake system and compensate for its expansion during operation.
- 2. Master brake cylinder: converts mechanical input force into hydraulic output pressure. The output hydraulic pressure is distributed from the master brake cylinder to two hydraulic circuits connecting the brake mechanisms of the diagonally located wheels of the vehicle.
- 3. Brake force distribution system: regulates the pressure of the brake fluid supplied to the working brake cylinders, distributing the braking force across the vehicle wheels.
- 4. Brake lines and hoses: transport brake fluid to/from the brake system components.
- 5. Braking mechanisms: convert input hydraulic pressure into mechanical force at the output.
The mechanical force from the brake pedal pressed by the driver is amplified by a vacuum booster, after which it is converted into hydraulic pressure in the master brake cylinder, which is then redistributed by a modulator valve and supplied to the working cylinders of the wheel brake mechanisms via pipes and hoses. The wheel brake mechanisms convert the hydraulic pressure back into mechanical force, pressing the brake pads against the brake discs of the wheels.
