Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts on the rear wheels while the vehicle is still on the ground.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and place jack stands for safety.
Remove the rear wheels by fully unscrewing the lug nuts.

3. Remove Brake Components

Remove the brake caliper by unscrewing the bolts holding it in place (typically 14mm or 15mm).
Suspend the caliper using a bungee cord or mechanics wire to avoid straining the brake line.
Take off the brake pads from the caliper bracket.

4. Inspect and Replace

Inspect the brake pads. If they are worn below the manufacturer's specified thickness, replace them.
Check the rotors for damage. If they are scored or warped, replace or resurface them.
Clean the caliper bracket and apply brake grease to the contact points of the new pads.

5. Reassemble

Reinstall new or resurfaced rotors if applicable.
Attach new brake pads to the caliper bracket.
Reinstall the brake caliper and tighten the bolts to the manufacturer's torque specification (usually 25-35 ft-lbs).
Reinstall the wheels and tighten the lug nuts in a star pattern to the specified torque.

6. Final Checks

Lower the vehicle and pump the brake pedal to ensure proper caliper engagement.
Inspect the brake fluid level and top off if necessary.
