Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent electrical accidents.

2. Remove Rear Wheels

Loosen lug nuts with a lug wrench.
Lift the rear of the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and take off the rear wheels.

3. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Check for uneven wear; replace pads if worn out.
- Measure rotor thickness; replace if below manufacturer specifications.
Replace Brake Pads:
- Remove caliper bolts using a socket set.
- Carefully slide caliper off the rotor.
- Remove old brake pads from caliper bracket.
- Install new pads, ensuring they are seated properly.
Check and Replace Rotors (if necessary):
- Remove the caliper bracket if needed to access the rotor.
- Remove the rotor from the hub by removing retaining screws if present.
- Install new rotors and secure them.

4. Inspect Calipers and Hardware

Check Caliper Function:
- Slide calipers back and forth to ensure smooth movement.
- Apply brake cleaner to the caliper slides and lubricate if necessary.
Replace Damaged Hardware:
- Replace any damaged or corroded hardware such as shims, clips, or bolts.

5. Reassemble and Reinstall

Reattach the caliper and ensure all bolts are torqued to specifications.
Reinstall the wheels and torque lug nuts to the manufacturer's specifications.
Lower the vehicle and reconnect the battery.
