Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to prevent electrical issues while working on the braking system.

2. Remove Wheel

Use a socket set to loosen the lug nuts on the wheel where the noise is coming from.
Lift the vehicle using 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.
- Carefully slide the caliper off the rotor and support it without putting stress on the brake line.
- Inspect brake pads for wear; replace if thickness is below 3mm.
Brake Rotors:
- Check for scoring, pitting, or warping on the rotor surface.
- If damaged, replace the rotor; if not, clean the rotor surface with brake cleaner.
Calipers:
- Inspect the caliper for any signs of leaks or damage.
- Ensure the caliper moves freely; lubricate slides if necessary with brake grease.

4. Reassemble

If components are replaced, install new brake pads and rotors according to the manufacturer's specifications.
Reinstall the caliper and torque the caliper bolts to factory specifications (typically around 20-30 ft-lbs).
Reattach the wheel and torque lug nuts in a star pattern to the recommended torque (typically 100-120 ft-lbs).

5. Final Check

Reconnect the battery and lower the vehicle.
Pump the brakes a few times to ensure proper seating of the pads and calipers.
Test drive the vehicle to confirm the squeaking noise is resolved.
