Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and set the parking brake.
Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and safety glasses.

2. Remove Wheels

Loosen the lug nuts on the front wheels while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Measure rotor thickness with a micrometer. If warping is detected or thickness is below specification, replace the rotors.
Replace Brake Pads:
- Remove the caliper bolts and slide the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Install new brake pads into the caliper bracket, ensuring proper orientation.
Reassemble:
- Reinstall the caliper over the new brake pads and tighten the caliper bolts to the manufacturer's specifications (typically around 25 ft-lbs).

4. Reinstall Wheels

Place the wheels back on the vehicle and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then tighten the lug nuts to the specified torque (usually around 76 ft-lbs) in a crisscross pattern.

5. Test Drive

Conduct a test drive to ensure the shaking is resolved. Monitor brake performance and listen for abnormal noises.
