Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Caution: Refer to Brake Dust Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
- Apply and fully release the parking brake 6 times. Verify that the park
brake pedal releases completely.
- Turn ON the ignition. Verify that the BRAKE indicator lamp is off.
If the BRAKE lamp is on, then check the following:
• | Ensure the parking brake is in release mode and fully returned to the
stop. |
• | Check the front park brake cable slack. Remove the slack in the front
park brake cable by pulling downward on the cable. |
- Raise and suitably support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the rear wheels and tires. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Adjust the drum brakes. Refer to
Drum Brake Adjustment
in Drum Brakes.
- Install the rear wheels and tires. Refer to
Tire and Wheel Removal and Installation
in Tires and Wheels.
- Adjust the park brake system by turning
the nut at the equalizer (2) while spinning both rear wheels. When either
rear wheel starts to drag, back off the nut one full turn.
- Lower the vehicle to curb height.
- Apply the park brake five clicks and check the forward rotation of the
rear wheels. With five clicks applied it should be very difficult to turn the wheels
by hand (should require 30 - 40N·m torque, measured with a torque wrench
on a wheel stud). With less than five clicks applied, wheels should turn easily by
hand. Readjust the equalizer nut as needed to obtain this condition.
- Release the parking brake. Verify the wheels rotate freely.
- Lower the vehicle.
