Q: How to Replace Disc Brake Pads?A: This procedure is applicable to both front and rear disc brakes. Begin by removing the brake fluid reservoir cap, loosening the wheel lug nuts, raising the vehicle securely on jackstands, and removing the respective front or rear wheels. Focus on one brake assembly at a time. For front pads, push the piston back using a C-clamp to make space for new brake pads. Then, spray brake system cleaner, remove the lower caliper bolt, swing the caliper up, remove the outer and inner brake pads along with shims and retainer clips, apply anti-squeal compound to new pads, install shims, inner and outer pads, and caliper pin dust boots, coat caliper bolts/sliding pins with grease, and reposition the caliper while tightening the lower bolt. For rear pads, remove the caliper shield bolts, shield, caliper mounting bolts, lift the caliper aside with a wire, remove outer and inner pads, and retainer, coat new pads with anti-squeal compound, install shims and pad retainers, retract and position the piston, and install the caliper protector. Install wheels, lower the vehicle, tighten lug nuts, apply/release brake pedal and hand brake lever, check brake fluid level, and test the brakes in a controlled area before driving in traffic.
