Disc brake pad replacement for rear disc brakes is similar to the process for the front pads. Begin by removing the cap from the brake fluid reservoir and extracting about two-thirds of the fluid, taking care to protect painted surfaces from brake fluid damage. Loosen the wheel lug nuts, raise the vehicle securely on jackstands, and block the wheels at the opposite end. Remove the wheels and work on one brake assembly at a time, using the assembled brake for reference if needed. Inspect the
Brake Disc carefully, and if machining is necessary, remove the disc to access the pads. Push the piston back into its bore using a large C-clamp, ensuring the master cylinder fluid does not overflow. On rear disc brakes, be cautious with the integral parking brake mechanism while depressing the piston. Wash the brakes with brake cleaner before disassembly, remove the lower caliper mounting bolt (and both if needed for the parking brake cable), pivot the caliper up while securing it, and remove the outer and inner brake pads along with the pad support plates. Clean and inspect the support plates for wear, replacing them if necessary, and lubricate the guide pins with high-temperature grease before reinstalling them. Ensure the new pads match the old ones and are equipped with new shims if applicable. Lubricate the ends of the new pads where they contact the anti-rattle clips, install the inner and outer pads, and for rear calipers, rotate the piston until it is fully depressed and align the notches with the caliper openings. Reinstall the caliper over the new pads, align the notch in the piston with the pin on the inner brake pad, and tighten the caliper mounting bolts to the specified torque. After completing the installation, firmly depress the brake pedal several times to ensure proper contact with the disc, check the brake fluid level, and add if necessary. Finally, if working on rear brakes, apply and release the parking brake four times.
