Adjusting the Park Brake
1. Raise the rear of the unit and place it on
stable jack stands. Engage the parking
brake and remove both rear tires/wheels.
2. With the parking brake still engaged,
remove all spring tension by loosening
the spring locknut. Unlock the jam nut
against the yoke and loosen the bolt until
the head is about 1/2 inch away from the
trunnion. Relock the jam nut against the
yoke. Tighten the spring locknut until bolt
head/trunnion gap closes to 1/8 to 1/4
inch.
3. Disengage the parking brake hand lever
and check that the spring is still under
tension. This is important in order to hold
the linkage from going over-center.
4. Repeat steps 2 and 3 on the opposite
brake band.
5. If the brake band is making noise while in operation, rattling, squealing, etc, it may be necessary to
readjust the parking brake band.
