Park Brake Adjustment

SETUP AND ADJUSTMENTS

1.Stop engine and remove key, release park brake and check the gap between the rear tire and the brake arm. The gap should be 1/8” to 1/4”.

2.If adjustment is needed, loosen the lock nut next to the yoke. Remove the pin from the front yoke so you can rotate the yoke on the adjust- ment link until the proper gap is achieved.

3.Make sure the brake arm on both sides does not touch the tire when the brake is in the off position. FIG - 4
