Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, caliper tool, torque wrench, brake cleaner, and OBD-II scanner.
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Gently slide the caliper off the rotor and suspend it to avoid stress on the brake line.
- Inspect the brake pads for uneven wear; replace if worn beyond specifications.
Brake Rotors:
- Check for warping by using a dial indicator or visually inspecting for uneven surfaces.
- If warped, replace the rotors.
- Clean the rotors with brake cleaner before reassembly.
Brake Calipers:
- Inspect caliper pistons for proper movement.
- Ensure caliper slides are lubricated and functioning correctly.

4. Reassemble Components

Replace or reinstall the brake pads and caliper.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts to the manufacturer’s torque specifications.

5. Final Checks

Reconnect the battery if it was disconnected during diagnostics.
Conduct a test drive to ensure vibrations are resolved.
