Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, brake cleaner, brake grease.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues while working on the brakes.

2. Lift the Vehicle

Loosen the lug nuts on the wheel where the squeaking is occurring.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper by unbolting it from the mounting bracket.
- Carefully slide the caliper off the brake pads.
- Check the pads for wear; if they are below the manufacturer's recommended thickness (usually 3mm), replace them.
Replace Brake Pads (if needed):
- Remove the old brake pads from the bracket.
- Clean the caliper bracket and apply brake grease to the contact points.
- Install new brake pads in the correct orientation.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Brake Rotors:
- Check for any scoring, cracks, or warping on the rotors. If any damage is found, consider replacing them.
Replace Brake Rotors (if needed):
- Remove the caliper bracket by unbolting it.
- Slide off the rotor; if it’s stuck, gently tap it with a rubber mallet.
- Install the new rotor ensuring it sits flush against the hub.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor, tightening bolts to the manufacturer's torque specifications (usually around 25-35 ft-lbs for caliper bolts).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the car and then torque the lug nuts to the specified value (typically 80-100 ft-lbs).
Reconnect the battery.
