Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, lug wrench, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise the Vehicle

Loosen the lug nuts on the front or rear wheel (depending on where the noise is originating).
Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket. (Torque specs: typically 25-35 ft-lbs)
Slide the caliper off the rotor and hang it using a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for thickness; replace if worn below 1/8 inch.
Apply brake grease to the back of the new pads to prevent noise and install them into the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for signs of damage such as scoring or excessive wear. If damaged, replace them.
To remove the rotor, unbolt it from the hub (usually 2-4 bolts) and slide it off.
Install the new rotor, ensuring it is clean and free of grease.
Torque the rotor bolts to manufacturer specifications (typically around 70-90 ft-lbs).

5. Reassemble Braking Components

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Test

Lower the vehicle from the jack stands.
Tighten the lug nuts in a star pattern to the manufacturer's specification (typically around 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper pad seating.
