Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a flat surface and parked securely.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a lug wrench.
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 Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the brake rotor and support it with a bungee cord or similar device (do not let it hang by the brake line).
Inspect the brake pads for wear. If they are less than 3mm thick, replace them.
Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new brake pads where they contact the caliper.
Install the new brake pads into the caliper bracket.

4. Inspect and Resurface/Replace Rotors

Check the rotors for warping or scoring. If scored or warped, they should be resurfaced or replaced.
If resurfacing, ensure the rotor thickness meets manufacturer specifications after machining.
If replacing, remove the rotor by removing the retaining screws or bolts.
Install new or resurfaced rotors onto the hub.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications (typically 20-30 ft-lbs).
Reinstall the wheel and hand tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer’s specifications (typically 75-85 ft-lbs).
Pump the brake pedal a few times to ensure proper brake pad seating.
Test drive the vehicle to ensure the squeaking noise has been resolved.
