2. Turn ON the ignition. Verify the red BRAKE warning lamp is not illuminated.
3. If the red BRAKE warning lamp is illuminated, verify the following:
* The park brake lever is in the fully released position and against the stop.
* There is no slack in the park brake cables.
4. If the red BRAKE warning lamp remained illuminated and there were no other visible causes, refer to Symptoms - Hydraulic Brakes.
5. Turn OFF the ignition. Symptoms - Hydraulic Brakes
6. Remove the console rear trim plate.
7. With the park brake lever in the released position, loosen the adjusting nut (1) enough to completely relieve tension on the front cable.
8. Raise and support the vehicle. Raise the vehicle just enough to allow rear tire and wheel assembly removal and rear drum adjustment. Refer to Vehicle Lifting.
9. Remove the rear tire and wheel assemblies.
10. Adjust the rear drum brakes.
11. Ensure there is no brake shoe drag after adjustment by rotating the brake drums. If drag exists, re-center the brake shoes and perform the brake shoe adjustment again.
