Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative terminal of the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Check for warping using a dial indicator or straight edge.
- If warped, proceed to replace the rotor.
Replace Brake Pads:
- Remove the caliper by loosening the caliper bolts with a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
- Remove the old brake pads and install new ones, ensuring they are properly seated.

4. Reinstall Components

Reinstall Brake Caliper:
- Place the caliper back over the new pads and rotor.
- Tighten the caliper bolts to the manufacturer’s specified torque (typically around 20-25 ft-lbs for most models).
Reattach Wheel:
- Place the wheel back on the hub, hand-tighten the lug nuts.
- Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (usually around 76-83 ft-lbs).

5. Test Drive

Reconnect the battery terminal.
Conduct a test drive to ensure the brakes function properly and the shaking is resolved.
