Solution

1. Preparation

Gather necessary tools and parts.
Safely elevate the vehicle using jack stands.
Disconnect the battery to avoid accidental deployment of electronic components.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper by unscrewing the caliper bolts with a socket wrench.
- Inspect the brake pads for wear; replace if the friction material is less than 3mm.
Replacement:
- Remove old pads and clean the caliper bracket.
- Install new brake pads ensuring they fit correctly in the caliper.
- Apply brake grease to the back of the pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the thickness of the rotors using a micrometer; replace if below manufacturer specifications.
Remove the rotor by unscrewing the retaining screw (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free from oil or grease.

5. Reassemble Components

Reinstall the brake caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper brake pad seating.
Test the brakes at low speed to confirm the noise has been eliminated.
