Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
Caliper gauge
OBD-II scanner

2. Remove Wheel

Loosen the lug nuts on the wheel with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for wear; they should be at least 1/8 inch thick.
Check the rotors for grooves or rust; if scored, they may require resurfacing or replacement.
Examine brake hardware for any signs of damage or wear.

4. Replace Brake Pads (if worn)

Remove the caliper by loosening the caliper bolts with a socket set.
Slide the caliper off the rotor and support it without straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are oriented properly and seated correctly.
Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer's specified torque.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque.
Pump the brake pedal a few times to seat the pads against the rotor.
Test drive the vehicle to ensure the squealing noise has been resolved.
