Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues, especially if working on electronic brake systems.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a socket set before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads. If they are below 3mm, they need replacement.
- Look for uneven wear patterns, which may indicate caliper or rotor issues.
Replacement:
- Remove the caliper by unscrewing the caliper bolts using the appropriate socket.
- Carefully slide the caliper off the rotor without damaging the brake line.
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to contact points of the new pads.
- Install the new brake pads in the caliper bracket.
- Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or exceed the manufacturer's wear limit, replace them.
Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
Install the new rotor and secure it in place.

5. Reassemble and Check Brake Fluid

Reinstall the wheel and torque the lug nuts to the recommended specifications.
Reconnect the battery.
Check the brake fluid level in the master cylinder and top off if necessary with the correct brake fluid type (usually DOT 3 or DOT 4).

6. Final Checks

Before driving, pump the brake pedal to ensure proper pad seating and brake function.
Conduct a test drive to confirm that the squeaking noise is resolved.
