Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment such as gloves and safety glasses.

2. Remove Wheels

Loosen the lug nuts slightly while the vehicle is still on the ground.
Jack up the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator.
- If warped beyond manufacturer specifications (usually more than 0.002 inches), replace the rotors.
Inspect Brake Pads:
- Check for uneven wear; replace if worn down to the wear indicators.
Clean Rotors:
- Use brake cleaner to remove dust and debris.

4. Reinstall Components

Reinstall the brake pads and rotors, ensuring they are properly aligned.
Torque the lug nuts to the manufacturer's specification (usually around 80-100 ft-lbs, check specific values for your model).
Reinstall the wheels and lower the vehicle.

5. Test Drive

After the repair, conduct a test drive to ensure the shaking has been resolved.
