Solution

1. Preparation

Gather tools and park the vehicle on a flat, stable surface.
Gather tools: jack, jack stands, lug wrench, runout gauge, caliper, and OBD-II scanner.
Disconnect the battery if electrical components will be handled.

2. Inspect and Replace Brake Rotors

Lift the Vehicle
- Use the jack to lift the front or rear of the vehicle as needed.
- Secure with jack stands.
Remove Wheels
- Use a lug wrench to remove the lug nuts and take off the wheels.
Check Rotor Condition
- Use a runout gauge to measure rotor warping. If it exceeds manufacturer specifications, replace the rotor.
Remove Old Rotors
- If rotors are warped, remove the caliper bolts and detach the caliper from the bracket.
- Slide the rotor off the hub.
Install New Rotors
- Position the new rotor on the hub.
- Reattach the caliper and torque bolts to manufacturer specifications.

3. Inspect and Replace Brake Pads

Check Brake Pad Condition
- Visually inspect the brake pads for uneven wear or thickness.
- If worn, remove the pads from the caliper bracket.
Install New Brake Pads
- Apply brake grease to the backing of the new pads.
- Insert the new pads into the caliper bracket and reattach the caliper to the rotor.

4. Reassemble and Test

Reinstall Wheels
- Place the wheels back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Reconnect Battery
- If disconnected, reconnect the battery.
Test Drive
- Conduct a test drive to ensure the shaking has been resolved.
