PARKING BRAKE ADJUSTMENT

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 effectiveness

2. Brake Rod 5. Spring

3. Return Nuts 6. Jam Nuts

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 in. (3.81 cm) between the jam nuts and the

trunnion and the clearance between the return nuts and

trunnion should measure 1/16 to 1/8 in. (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 in. (3.81 cm) clearance between the jam nuts

and trunnion.

Tighten jam nuts together.

Turn the return nuts clockwise to decrease the

distance or counterclockwise to increase the distance

until there is 1/16 to 1/8 in. (1.59 to 3.18 mm) between

the return nuts and trunnion.

5. Tighten return nuts together.
