Drum-type parking brake with mechanical drive (Fig. 1)
The parking brake drive is connected by lever and rod to lever 13 of the brake valve, which ensures that when the vehicle is braked with the parking brake, the service brake system of the trailer (semi-trailer) is activated.
The auxiliary brake consists of a drive and two actuators installed in the connector of the exhaust pipes of the muffler
The pneumatic brake booster (Fig. 1) is designed to convert the energy of compressed air into the required pressure of the working fluid in the hydraulic part of the brake drive
