3.2.8 PARKING BRAKE

The parking brake is used to immobilise and prevent the trailer from moving while standing
motionless. The trailer is equipped with parking brake with crank mechanism – figure (3.15).
To immobilise the trailer turn the mechanism crank (1) clockwise fully home. When rotating
the crank, tension of the steel cable (2) stretches another cable routed through rollers (3).
Cables are connected to expander levers (4) of the wheel axle. Tightening the cable causes
tilting of the expander levers, which part the jaws of the brake shoes immobilising the trailer.
