Solution

1. Preparation

Tools Required: Socket set, lug wrench, brake cleaner, jack stands, tire iron.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety.

2. Wheel Removal

Loosen the lug nuts on the front or rear wheels (depending on where the noise is coming from).
Raise 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

Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the brake rotor.
3. Inspect the brake pads for wear; they should have at least 1/8 inch of material.
4. If worn, replace with new brake pads. Apply brake grease to the backing of the new pads to prevent squealing.
5. Reinstall the caliper and torque the bolts to the manufacturer’s specifications (typically 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or warping.
2. If damaged, remove the rotor by unscrewing the retaining screws or caliper bracket if needed.
3. Install new rotors, ensuring they are clean and free of grease.
4. Reassemble calipers and wheels.

5. Brake Fluid Check and Replacement

Check the brake fluid level in the master cylinder reservoir.
If the fluid is dirty or low, flush the brake system and replace with the manufacturer-recommended brake fluid.
