WARNING: This page is about a different car, the 2003 Buick Regal, 2003 Buick Century, 2002 Buick Regal, and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
- Apply and fully release the parking brake 6 times. Verify that the park brake pedal releases completely.
- Turn the ignition on. Verify that the Red 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 support the vehicle. Remove the rear wheels and tires.
- Adjust the drum brakes. See DRUM BRAKE ADJUSTMENT .
- Install the rear wheels and tires. 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. See Figure .
- Lower the vehicle to curb height.
- Apply the park brake 5 clicks and check the forward rotation of the rear wheels. With 5 clicks applied it should be very difficult to turn the wheels by hand (should require 30-40 N.m of torque, measured with a torque wrench on a wheel stud). With less than 5 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.
