Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Rear Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen lug nuts on the rear wheel slightly while the vehicle is on the ground.
2. Raise the rear of the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the rear wheel.

3. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, and a C-clamp.
Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts and lift it away from the rotor.
2. Use a C-clamp to compress the caliper piston slowly.
3. Inspect the brake pads for wear; replace if they are less than 3mm thick.
4. Check the rotor for warping or grooves; replace if damaged.
5. Clean the caliper and rotor surfaces with brake cleaner.
6. Reinstall new brake pads and caliper, ensuring bolts are torqued to manufacturer specifications.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or hose, brake fluid.
Sub-steps:
1. Locate the brake bleeder valve on the caliper.
2. Attach the brake bleeder kit or a hose to the valve.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to allow air and fluid to escape, then close it.
5. Repeat until no air bubbles are present.
6. Ensure brake fluid level remains adequate in the master cylinder.

5. Reassemble and Test

Reinstall the rear wheel and lower the vehicle.
Tighten the lug nuts to the recommended torque specifications.
Conduct a test drive to evaluate braking performance.
