Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Remove the Wheel

Using a jack, lift the rear of the vehicle and place it on jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket wrench and take off the caliper.
Hang the caliper using a bungee cord to avoid strain on the brake line.
Remove the old brake pads and inspect the backing plates for wear.
If necessary, replace with new brake pads. Ensure they are the correct type for the vehicle model.

4. Inspect and Resurface/Replace Rotors

Check the brake rotor surface for scoring or warping.
If scoring is present, consider resurfacing the rotors; if they are warped beyond specification, replace them with new rotors.
Use a torque wrench to tighten rotor bolts to manufacturer specifications.

5. Reassemble

Reinstall the brake caliper over the new pads.
Tighten caliper bolts to manufacturer torque specifications.
Reinstall the wheel and lug nuts, and lower the vehicle back to the ground.
