Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the location of the brake noise.
Secure the vehicle with jack stands.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord (do not hang by the brake line).
Remove the old brake pads; check for wear indicators.
Install new brake pads, ensuring they are seated correctly.

5. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove them by unscrewing the rotor screws (if applicable) and pulling them off the hub.
Clean the hub surface to ensure proper contact with the new rotor.
Install new rotors, securing them in place.

6. Reassemble and Test

Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications.
Reattach the wheel and tighten the lug nuts in a crisscross pattern.
Lower the vehicle and pump the brake pedal to seat the pads before test driving.
