ROUTINE MAINTENANCE
Under normal operating conditions the parking brake is maintenance free.
The parking brake is spring actuated. When the machine is operating and the brake is
supplied with air pressure, it is released. If at, any point the machine loses air pressure (i.e.
it is not running) the brake will be activated.
Adjustment is normally unnecessary.
To confirm appropriate setting:
Parts are under spring and air pressure. Also the machine must be running to
confirm brake adjustment and you are adjusting the braking system. Chock the
wheels before beginning the procedure.
Back off jam nut (1). This will free up the brake actuator yoke (2). Slide the yoke to the right
as far as it will go. (This will be the point at which the drum and rotor contact. Then move
the yoke 1/4” to the left and adjust jam nut until it is tight against the yoke.
