Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Remove Wheel

Loosen the lug nuts on the wheel using a socket set.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Rotors:
- Check the rotor surface for warping or scoring.
- If warped, replace rotors with new ones. Torque new rotors to manufacturer specifications.
Brake Pads:
- Remove caliper by unscrewing caliper bolts with a socket wrench.
- Slide out the old brake pads and inspect for wear.
- Replace with new pads if worn. Ensure they are compatible with the rotors.
Caliper:
- Check caliper for proper movement.
- If binding is detected, consider replacing the caliper. Lubricate caliper slides if necessary.

4. Inspect Suspension Components

Check for worn bushings, ball joints, and control arms.
Replace any damaged or worn components.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to manufacturer specifications.
Reconnect the battery.

6. Brake Bedding

Drive the vehicle in a safe area and perform a series of controlled stops to bed the new brake pads and rotors.
