ROUTINE MAINTENANCE Under normal operating
conditions the parking brake is maintenance free.
The parking brake is spring actuated. When the ma-
chine is operating and the brake is supplied with air
pressure, it is released. If at, any point the machine los-
es 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 ma-
chine 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 (A). This will free up the brake actua-
tor yoke (B). 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.
