operation:

The brake pedal valve (13.02) uses the stored air on the compressed air tanks (5.01), braking the vehicle when the driver activates the brake pedal. This guarantees that the vehicle has a gradual and proportional braking to the effort applied onto the brake pedal. After being activate, the valve (13.02) sends air to the pneumatic cylinders (20.02).

The pneumatic cylinders (20.02) act when the vehicle driver steps on the brake pedal, multiplying the applied force and actuating the hydraulic cylinder (19.01).

The hydraulic cylinder (19.01) uses the oil of the tanks (34.01) and sends it to the wheels' hydraulic cylinders.
