Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, and safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks. Always wear safety goggles when working with brake components.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts on the rear wheels.
Jack the vehicle up and secure it with jack stands.
Remove the rear wheels.

3. Remove Brake Components

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord or wire to avoid putting stress on the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Replace Components

Inspect the brake pads for wear; if they are worn down to the backing, replace them.
Check the rotors for damage. If they are scored or below the minimum thickness, they should be replaced or resurfaced.
Clean the caliper bracket and contact points with brake cleaner to remove any debris.

5. Installation

Install new brake pads into the caliper bracket.
If replacing rotors, install new rotors onto the hub.
Reattach the caliper over the new pads and rotor, ensuring it sits correctly.
Torque the caliper bolts to the manufacturer's specifications.

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications.
