Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure safety glasses and gloves are worn.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where the issue is felt).
Secure the vehicle with jack stands.

3. Remove Wheel

Using a socket wrench, remove the lug nuts and take off the wheel.
Tools Required: Socket set, impact wrench (optional).

4. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping or scoring. Use a dial indicator for precise measurement.
- If warped, replace with new rotors.
Inspect Brake Pads:
- Check for thickness; replace if below manufacturer specifications.
- Ensure pads are properly seated in the caliper.
Clean Components:
- Use brake cleaner to remove any debris or dust from the calipers and rotors.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground.
Torque lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

6. Final Inspection

Perform a test drive to ensure the shaking is resolved.
Check brake operation and listen for abnormal noises.
