Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Raise the Vehicle

Lift the front of the vehicle using a hydraulic jack.
Secure with jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts from the front wheels.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors

Inspection:
- Check the surface of the rotors for grooves or warping using a dial indicator.
Replacement:
- If warped, unbolt the caliper bracket and remove the rotor.
- Install new rotors, ensuring they are properly seated.
- Torque the rotor bolts to manufacturer specifications.

5. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket.
Check the brake pads for wear; if below minimum thickness, replace them.
Install new brake pads, ensuring they are aligned properly within the caliper.

6. Reassemble and Reinstall Wheel

Reattach the caliper and ensure it is secured.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

7. Test Drive

Conduct a test drive to ensure the issue is resolved and check for any remaining shaking.
