Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Rear Wheel

Use a jack to lift the rear of the vehicle and support it with jack stands.
Remove the lug nuts with a socket wrench and take off the rear wheel.

3. Remove Brake Components

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.
Take out the old brake pads from the caliper bracket.

4. Inspect and Replace Parts

Check the brake rotor for damage; if warped or excessively worn, replace it.
If the brake pads are worn below the manufacturer's specifications (usually 3mm), replace with new pads.
Inspect caliper condition and replace if leaking or damaged.

5. Reassemble Brake System

Install new brake pads into the caliper bracket.
Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specification (usually 25-35 ft-lbs).
Reinstall the rear wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle from the jack stands.
Tighten the lug nuts to the manufacturer's torque specification (usually 100-150 ft-lbs).
Reconnect the battery and pump the brake pedal a few times to seat the new pads.
