Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, C-clamp or brake caliper tool.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Wear safety goggles and gloves.

2. Remove the Rear Wheel

Loosen the lug nuts on the rear wheel using a lug wrench.
Raise the rear of the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the rear wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using a socket set.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord or rope to avoid stressing the brake line.
If necessary, compress the caliper piston using a C-clamp or brake caliper tool to facilitate the removal of the caliper.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake cleaner to remove dust and debris.
Install the new brake pads into the caliper bracket, ensuring they are seated properly.

5. Reinstall Caliper and Wheel

Reinstall the caliper over the new brake pads and align it with the mounting bracket.
Secure the caliper by tightening the mounting bolts to the manufacturer’s specified torque (typically around 25-35 ft-lbs).
Reinstall the rear wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle to the ground and remove the jack stands.
Tighten the lug nuts to the specified torque (usually 75-85 ft-lbs).
Repeat the process for the other rear wheel if necessary.
Pump the brake pedal several times to ensure proper brake pad seating and to restore brake pressure.
