Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift Vehicle

Use a jack to lift the front of the vehicle and secure with jack stands.
Remove the front wheels using a socket set.

3. Inspect Brake Rotors

Check the rotors for warping using a dial indicator or straight edge.
If warped, proceed to replace the rotors.
Remove the brake caliper by unbolting it and hanging it with a wire (do not let it dangle by the brake line).
Remove the rotor by unbolting it (if applicable) or sliding it off the hub.

4. Replace Brake Rotors

Install new rotors, ensuring they are properly seated.
Reinstall the brake caliper and torque the bolts to manufacturer specifications (typically around 80-100 ft-lbs).
If the brake pads are worn, replace them according to the next step.

5. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool.
Install new brake pads, ensuring they are properly aligned.
Reinstall the caliper over the new pads.

6. Reassemble and Lower Vehicle

Reattach the wheels and torque lug nuts to manufacturer specifications (usually around 75-85 ft-lbs).
Lower the vehicle from the jack stands and remove the jack.

7. Test Drive

Perform a test drive to ensure that the shaking has been resolved and that braking is smooth.
