Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather tools and parts required for the repair.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts.
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 Rotors:
- Check for warping or damage. If found, replace the rotors.
- If rotors are within specifications, clean them with brake cleaner.
Inspect Brake Pads:
- Remove the caliper bolts with a socket set.
- Slide the caliper off the rotor and inspect pads for wear. Replace if worn.
Reinstall Components:
- If rotors or pads were replaced, install new components in reverse order. Ensure proper alignment and torque specifications for caliper bolts (typically 25-30 ft-lbs).

4. Reinstall Wheel and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
Test drive the vehicle to ensure the shaking has been resolved.
