Solution

1. Preparation

Gather tools and parts necessary for the repair.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect Brake Components

Remove the Wheel
- Use a lug wrench to loosen the lug nuts before raising the vehicle. After lifting, completely remove the lug nuts and take off the wheel.
Examine Brake Pads and Rotors
- Visually inspect the brake pads for thickness. Replace if they are below 3mm.
- Check the rotors for evenness using a dial indicator; replace if warped beyond specifications (usually more than 0.002 inches).

3. Replace or Resurface Brake Rotors (if necessary)

Remove Caliper
- Use a socket set to remove the caliper mounting bolts. Hang the caliper using a wire to avoid straining the brake line.
Remove Rotor
- If the rotor is secured with screws, remove them and slide the rotor off the hub. If it’s stuck, gently tap with a hammer.
Install New or Resurfaced Rotor
- Clean the hub surface, then install the new or resurfaced rotor. Secure with screws if applicable.

4. Reassemble Brake System

Reattach Caliper
- Place the caliper back over the rotor and secure it with the mounting bolts. Torque to manufacturer specifications.
Install Wheel
- Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the specified value.

5. Test Drive the Vehicle

After reassembly, take the vehicle for a test drive to ensure that the shaking has been resolved.
