Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical issues during the repair.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for warping using a dial indicator; if warped beyond specifications (usually more than 0.002 inches), replace the rotors.
Replace Rotors (if necessary):
- Remove caliper bolts using a socket set and slide the caliper off the rotor.
- Hang the caliper using a bungee cord to avoid stress on the brake line.
- Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it is properly seated and secured with retaining screws.

4. Inspect and Replace Brake Pads

Remove the caliper bracket by unscrewing it.
Take out the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are oriented correctly and seated properly.
Reattach the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (usually around 76 ft-lbs).
Reconnect the battery and perform a test drive to ensure the issue is resolved.
