Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Disconnect the 12V battery before working on the braking system.

2. Wheel Removal

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a socket set. Check the torque specification for the lug nuts during installation.

3. Inspect and Replace Brake Components

Brake Pads:
- Inspect pads for wear; replace if thickness is below the manufacturer's specification.
- Use a brake cleaner to clean the caliper and mounting surfaces.
Brake Rotors:
- Measure rotor thickness; if below specifications or warped, replace them.
- Resurface rotors if within thickness limits but showing signs of uneven wear.
Reassembly:
- Install new or resurfaced rotors and new brake pads.
- Torque bolts to the manufacturer's specifications.

4. Suspension Inspection (if needed)

Inspect control arms, bushings, and tie rods for wear.
Replace any damaged or worn components.
Reassemble and torque all suspension parts to manufacturer specifications.
