Construction and principle of operation

3.6 PARKING BRAKE

The parking brake is used to immobilize
the trailer during parking. The brake
crank mechanism body (1) is welded to
the bracket located to the left longitudinal
member of the lower frame.
The steel cable (2) is guided through the
wheels (3), connects the crank mechanism
through the arms (5) to the expander levers
of the rear axle (6) - figure (3.11).
Tensioning the cables (turning the crank
mechanism clockwise) causes swinging of
the expander levers, which by opening the
brake shoes immobilize the trailer
