Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety if working on electrical components.

2. Remove Wheel

Sub-steps:
- Loosen the lug nuts on the affected wheel while the vehicle is still on the ground.
- Raise the vehicle using a jack and secure it on jack stands.
- Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Sub-steps:
- Remove the caliper by unbolting it from the bracket (typically requires a socket).
- Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.
- Remove the brake pads from the caliper bracket.
- Inspect the brake rotor for warping using a straight edge or a runout gauge. If warped, replace the rotor.
- If pads are worn unevenly or below the manufacturer's recommended thickness, replace them.
- Install new brake pads and rotor (if replaced), ensuring proper orientation and fit.

4. Reassemble and Adjust

Sub-steps:
- Reattach the caliper over the new pads and rotor.
- Torque the caliper bolts to the manufacturer's specifications (check service manual for exact values).
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and fully tighten the lug nuts to the specified torque.

5. Final Checks

Sub-steps:
- Reconnect the battery if it was disconnected.
- Pump the brake pedal to ensure proper pad seating and brake function before driving.
- Test drive the vehicle at low speeds to check for vibration.
