Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and wear safety glasses.

2. Lift the Vehicle

Loosen the lug nuts on the rear wheels slightly before raising the vehicle.
Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the brake pads and hang it using a bungee cord to avoid strain on the brake line.
3. Remove the old brake pads from the bracket.
4. Compare the thickness of the old pads with new ones to ensure replacement is necessary.
5. If the pads are worn, install new brake pads into the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Inspect the rotors for wear, scoring, or warping.
2. If damaged, remove the rotor by unscrewing the rotor retaining screws (if applicable) and sliding it off the hub.
3. Install new rotors by reversing the removal process and ensuring they are properly aligned.

5. Reassemble Braking System

Sub-steps:
1. Reattach the caliper over the new brake pads.
2. Tighten the caliper bolts to the manufacturer’s torque specifications.
3. Reinstall the rear wheels and hand-tighten the lug nuts.

6. Lower the Vehicle and Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts in a star pattern to the specified torque.
Pump the brake pedal several times to ensure the pads seat properly against the rotors.
