SETUP AND ADJUSTMENTS
Park Brake Adjustment
When the park brake is on, the spring should
measure 2 3/4” to2 7/8” and have a 1/4”-3/8” gap
between the brake yoke and the washer on the
lower brake rod.
If the spring needs adjusting follow these steps:
1. Apply the park brake.
2. Keep the lower brake rod from turning using a
9/16” wrench on the double nuts.
3. Turn the 3/8F nut at the the end of the spring
the proper direction to achieve the correct
measurement (2 3/4” - 2 7/8”).
4. Repeat on otherside if necessary.
