Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is on a flat surface and engage the parking brake.
Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a socket set.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the appropriate socket.
2. Slide the caliper off the brake rotor and hang it using a bungee cord to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of damage or leaking fluid.
5. Install new brake pads into the bracket, ensuring they are properly seated.
Tools Required: Socket set, bungee cord, brake cleaner.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Remove the caliper bracket by unscrewing its mounting bolts.
2. Slide the rotor off the hub; if it’s stuck, tap gently with a rubber mallet.
3. Inspect the rotor for wear; if it's warped or deeply scored, replace it.
4. Clean the new rotor with brake cleaner before installation.
5. Reinstall the rotor onto the hub and secure the caliper bracket back in place.
Tools Required: Socket set, rubber mallet, brake cleaner.

4. Reassemble and Test

Sub-steps:
1. Reattach the caliper and tighten the bolts to the manufacturer’s torque specifications.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and fully tighten lug nuts to the specified torque.
4. Pump the brake pedal to ensure proper pad seating before driving.
Tools Required: Torque wrench.
