Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, and a brake pad tool (if needed).
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear appropriate personal protective equipment (gloves, safety glasses).

2. Inspect and Replace Brake Components

Remove Wheel: Use a lug wrench to remove the rear wheel covering the brake assembly.
Inspect Brake Pads and Rotors:
- Check thickness of brake pads; replace if worn below the minimum thickness.
- Inspect the rotor surface for scoring or warping; replace if necessary.
Remove Brake Caliper:
- Unbolt the caliper from its mounting bracket using a socket set.
- Hang the caliper using a wire or bungee to avoid stressing the brake line.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper orientation.
Reassemble Brake Components:
- Reattach the caliper and torque bolts to the manufacturer’s specifications.
- Reinstall the wheel and torque lug nuts in a star pattern.

3. Inspect Rear Suspension

Check Shock Absorbers: Look for leaks or damaged mounts; replace if necessary.
Inspect Bushings and Struts: Check for cracks or excessive wear; replace worn components.
Reassemble: Ensure all components are secure, and lower the vehicle.
