ADJUSTING THE PARKING BRAKE
The parking brake might need adjustment over time and
after new brake pads have been installed.
NOTE:
After installing new brake pads in the calipers,
they must be burnished by driving for a short distance
(about 100 feet) with the brake on. To do this, bring the
parking brake lever part-way up while driving in a straight
line. This quickly breaks-in the pads for maximum effec-
tiveness.
Check Adjustment
NOTE:
Be sure to check the parking brake on both sides
of the unit (Figure 14).
With the parking brake engaged, the spring length should
measure 1 1/2" between the jam nuts and the trunnion
and the clearance between the return nuts and trunnion
should measure 1/16 to 1/8" (1.59 to 3.18 mm). If either
of these measurements is off, adjust the parking brake
appropriately.
Adjust the Parking Brake
1. Engage the parking brake.
2. Turn the jam nuts clockwise to compress the spring
or counterclockwise to extend the spring until there
is 1-1/2" (3.81 cm) clearance between the jam nuts
and trunnion.
3. Tighten jam nuts together.
4. Turn the return nuts clockwise to decrease the
distance or counterclockwise to increase the
distance until there is 1/16 to 1/8" (1.59 to 3.18 mm)
between the return nuts and trunnion.
5. Tighten return nuts together.
