The parking brake is mechanically driven by lever 3 (see fig. Parking brake drive parts), which, together with the return lever, is mounted on a bracket fixed to the floor of the body. The return lever is connected with a pin to the front cable 2, the other end of which passes through the hole in the guide 9 of the rear cable and a nut and a lock nut are screwed onto the threaded end of the cable. The movement of the front cable is guided by roller 8.
The middle part of the rear cable passes through the groove of the guide 9, the tension of which is regulated by a nut screwed onto the threaded lug of the front cable. A spacer sleeve 10 is installed between the guide 9 and the adjusting nut. The ends of the rear cable pass through the sheath, one end of which is attached to the brake shield, and the other end is installed in the groove of the body bracket.
At the rear ends of the cable there are tips, each of which is connected to the hook of the lever 18 (see fig. Rear wheel brake) manual drive pads. This lever is pivotally attached to the brake shoe with a finger and rests with its upper part against the groove of the expander bar 20. The rib of the brake shoe enters the opposite groove of the bar.
