MAINTENANCE
Parking Brake Cable Freeplay Adjustment
1. Inspect and perform any needed service on the brake pads before
adjusting parking brake cable freeplay.
2. Make sure the parking brake is NOT set (lever is DOWN).
3. Pull the brake cable back to inspect freeplay between the cable end
and the caliper bracket. Freeplay should be 1/16" - 1/8" (1.5-3 mm).
4. To adjust freeplay,
loosen the jam nut.
Turn the in-line
adjuster nut outward to
decrease freeplay. Turn
the adjuster nut inward
to increase freeplay.
5. Tighten the jam nut
against the adjuster nut.
Parking Brake Adjustment
1. Inspect and perform any needed service on the brake pads before
adjusting the parking brake.
2. Position the vehicle on a level surface. Place the transmission in
neutral.
3. Carefully elevate the rear of the vehicle slightly. Use an appropriate
lift.
4. Loosen the jam nut on the parking
brake adjustment bolt.
5. While rotating the rear wheels by
hand, tighten the adjustment bolt
until significant brake drag is
detected. Then back the adjustment
bolt out 1/4 turn.
6. Hold the adjustment bolt in place
and tighten the jam nut securely
against the lever arm.
7. Check parking brake lever movement. Verify that the rear wheels
rotate freely with the parking brake off (lever in DOWN position)
and that the vehicle will not move when the parking brake is applied
(lever in UP position).
8. Verify that the park brake lever stays in the UP position when the
brake is fully applied.
