Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, brake cleaner, torque wrench, socket set.
Safely park the vehicle on a level surface and engage the parking brake.
Place wheel chocks around the front wheels for added safety.

2. Raise the Vehicle

Loosen the lug nuts on the rear wheels slightly while the vehicle is still on the ground.
Use the jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using the lug wrench.

3. Remove Brake Components

Sub-steps:
- Remove the caliper mounting bolts with the socket set.
- Carefully slide the caliper off the rotor; support it with a bungee cord or rope to avoid stressing the brake line.
- Remove the brake pads from the caliper bracket.

4. Inspect and Replace

Sub-steps:
- Inspect the brake pads for wear; replace if the friction material is less than 3mm thick.
- Check the rotors for damage; if warped or excessively worn, they may need resurfacing or replacement.
- Clean the caliper and bracket with brake cleaner.
- Apply brake grease to the backing of the new brake pads and the caliper contact points.
- Install the new brake pads and reattach the caliper.

5. Reassemble and Lower Vehicle

Reinstall the caliper mounting bolts and torque them to the manufacturer's specifications.
Reattach the rear wheels and hand-tighten the lug nuts.
Lower the vehicle to the ground and fully tighten the lug nuts in a crisscross pattern.
