Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove Wheels

Using a lug wrench, loosen the lug nuts on the affected wheel.
Raise the vehicle with a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper bolts using a socket wrench and lift the caliper off the rotor. Check the thickness of the brake pads; replace if they are worn down.
Brake Rotors: Measure the rotor thickness using calipers. If the thickness is below specifications or if warping is detected, replace the rotors. Clean the rotor surfaces using brake cleaner.

4. Replace Rotors and Pads

If rotors are warped or worn, remove the rotor retaining screws if present and slide the rotor off the hub. Install the new rotor, ensuring it’s properly seated and secured.
Apply anti-squeal lubricant on the back of the new pads and install them into the caliper bracket. Reposition the caliper over the pads and secure it with the caliper bolts, tightening to the manufacturer’s specified torque.

5. Reassemble Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque.
Reconnect the negative battery terminal.

6. Test Brakes

Before driving, pump the brake pedal several times to ensure proper pad and rotor contact.
Take the vehicle for a test drive to ensure the shaking has been resolved.
