Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts on the rear wheel using a lug wrench.
2. Use a jack to lift the vehicle and place it securely on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Tools Required: Socket set, brake cleaner, torque wrench.
Sub-steps:
1. Remove the caliper bolts using a socket set and slide the caliper off the rotor.
2. Suspend the caliper with a bungee cord or hang it to avoid stressing the brake line.
3. Take out the old brake pads and inspect the caliper for any signs of damage or sticking.
4. Clean the brake rotor with brake cleaner and inspect for grooves or warping.
5. If the rotor is damaged, replace it with a new rotor. If not, it's fine to reuse.
6. Install new brake pads into the caliper bracket.
7. Reinstall the caliper over the new pads and secure it with the caliper bolts, tightening to manufacturer specifications.

4. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to the specified torque.
3. Pump the brake pedal a few times to seat the new pads.
