PARKING BRAKE ADJUSTMENT
Figure 19
The parking brake might need adjustment over time
and after new brake pads have been installed.
NOTE: After installing new brake pads in calipers, they
must be burnished by driving for a short distance
(about 100 feet) with the brake on. To do this, bring
parking brake lever part-way up while driving normally
(in a straight line).
Check Adjustment
NOTE: Be sure to check parking brake on both sides of
unit (Figure 19).
With parking brake engaged, spring length should
measure 1-1/2 in. (3.81 cm) between jam nuts and
trunnion. The clearance between return nuts and
trunnion should be 1/16 to 1/8 in. (1.5 to 3.1 mm). If the
measurements are not within specifications, adjust the
parking brake.
Adjusting the Parking Brake
1. Engage parking brake.
2. Turn jam nuts clockwise to compress spring or
counter clockwise to extend spring until there is
1-1/2 in. (3.81 cm) clearance between jam nuts
and trunnion.
3. Tighten jam nuts together.
4. Turn return nuts clockwise to decrease the
distance or counter clockwise to increase the
distance until there is 1/16 to 1/8 in. (1.5 to 3.1 mm)
between return nuts and trunnion.
5. Tighten return nuts together.
