The manufacturer recommends replacing the pad shims and wear indicators whenever the pads are replaced. Begin by removing the cap from the brake fluid reservoir, then loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jack stands while blocking the rear wheels. Remove the wheels and work on one brake assembly at a time, using the assembled brake for reference if necessary. Inspect the brake disc carefully, and if machining is necessary, remove the disc to also take out the pads. For front brakes, push the piston back into its bore using a C-clamp to create space for the new pads, ensuring the master cylinder fluid does not overflow. For front brake replacement, wash the brakes with brake cleaner, remove the caliper lower mounting bolt while holding the caliper pin, swing the caliper up and secure it, then remove the inner and outer pads along with the support springs. Clean and lubricate the caliper pin, coat the backs of the new pads with brake grease, clean the shims, and install them on the new pads before reinstalling the support springs and ensuring the pad surfaces are clean. Compress the piston with a C-clamp, swing the caliper down, and install the lower mounting bolt, tightening it to the specified torque. For rear brake replacement, spray the brake assembly with brake cleaner, hold the caliper pin while removing the mounting bolt, and hang the caliper assembly to relieve tension on the brake hose. Remove the anti-rattle springs, inner pad, and outer pad, keeping track of the order of components for reinstallation. Clean the inner anti-squeal shim, install the outer shim, clean and lubricate the caliper pins, and check the rubber boots for damage. Use a special tool or needle-nose pliers to retract the caliper pistons, then install the pads and anti-rattle springs securely. After reinstalling the caliper, tighten the mounting bolts to the specified torque, depress the brake pedal a few times to bring the pads into contact with the disc, check the brake fluid level, and tighten the wheel lug nuts to the specified torque. Finally, check the operation of the brakes carefully before placing the vehicle into normal service, noting that pushing in the caliper piston or operating the brake pedal for the first time could cause a diagnostic trouble code to appear.
