Disc brake pads must be replaced on both front or both rear wheels at the same time-never replace the pads on only one wheel. Also, the dust created by the brake system is harmful to your health. Never blow it out with compressed air and don't inhale any of it. An approved filtering mask should be worn when working on the brakes. Do not, under any circumstances, use petroleum-based solvents to clean brake parts. Use brake system cleaner only! This procedure applies to front and rear disc brakes. Remove the cap from the brake fluid reservoir and remove about two-thirds of the fluid. Brake fluid will damage paint. Cover all painted surfaces around the work area and be careful not to spill fluid during this procedure. Clean any spilled fluid immediately and rinse the area with lots of water. Loosen the wheel lug nuts, raise the end of the vehicle you're working on and support it securely on jack stands. Block the wheels at the opposite end. Remove the wheels. Work on one brake assembly at a time, using the assembled brake for reference if necessary. Inspect the brake disc carefully. If machining is necessary, follow the information to remove the disc, at which time the pads can be removed as well. On front brakes and rear brakes with parking brake shoes (instead of actuator-type calipers), push the piston back into its bore to provide room for the new brake pads. A C-clamp can be used to accomplish this. As the piston is depressed to the bottom of the caliper bore, the fluid in the master cylinder will rise. Make sure that it doesn't overflow. If necessary, siphon off some of the fluid. Do not attempt to depress the piston into the caliper on later models with parking brake actuator-type calipers. Once you have installed the new pads, proceed. Install the wheel and lug nuts, lower the vehicle and tighten the lug nuts to the torque. Apply and release the brake pedal several times to bring the pads into contact with the brake discs. Check the brake fluid level and add fluid, if necessary. Check the operation of the brakes in an isolated area before driving the vehicle in traffic.
