Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and use wheel chocks on the front wheels.
Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench, C-clamp or brake caliper tool.

2. Raise the Vehicle

Loosen the lug nuts on the rear wheels slightly while the vehicle is on the ground.
Lift the rear of the vehicle using a jack and secure it with jack stands.
Remove the rear wheels completely.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and use a socket wrench to remove them.
Carefully slide the caliper off the rotor; support it with a bungee cord or similar to avoid stress on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Use a brake cleaner to clean the caliper bracket and rotor surface.
Compare new brake pads with old ones to ensure proper fit.
Install the new brake pads into the caliper bracket.

5. Compress the Brake Caliper

Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing.
Ensure the piston is fully seated to allow for new pads.

6. Reassemble the Brakes

Slide the caliper over the new brake pads and rotor.
Reinstall and torque the caliper mounting bolts to the manufacturer’s specifications (usually around 25-30 lb-ft).
Reinstall the rear wheels and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque (usually around 80-100 lb-ft).
