The parking brake can be verified by clicking the lever five times to be sure it is fully engaged, any less and it might not be fully released consequently causing the vehicle to drag under the brake and any more and it may not hold the car on an incline. A method of improving its efficiency is to park on a hilly slope with the transmission on Neutral and the parking brake turned on so that the car moves and there is need to change it. The rear brakes are automatically adjusted and usually do not need any service unless the parts such as the brake drums, brake shoes, wheel cylinders and brakes cables are changed. The first step is to block the front wheels, lift the rear of the car, and hold it up well on jackstands and then remove the rear wheels. Once the center console has been taken out, press and release the brake pedal a few times followed by the parking brake, this is to center the cables. When the rear drum brake model is used, turn parking brake to the fourth notch, loosen the adjusting nut until the rear wheels become hard to turn then release the parking brake all the way and make sure the rear wheels turn freely. Calibrate with the number of clicks of the ratchet of the parking brake when in full engagement, and loosen the locknuts. When using rear disc brakes, place 1/16-inch feeler gauge between the caliper lever and the stop and tighten the adjusting nut until one can barely drag. Once the gauges are removed, turn on the parking brake and release the brake, with a 3/64-1/8-inch gap between the two, and ensure the brake is holding and the wheels of the back do not drag when turned. Lastly, the removal is reversed with installation.
