Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Brake cleaner
- Brake pad spreader tool
- Safety goggles and gloves
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported before working under it.
- Disconnect the battery if working on electronic brake components.

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads; they should be at least 3mm thick.
- If worn, proceed to replace them.
Replacement:
- Remove the caliper by loosening the caliper bolts.
- Carefully slide the caliper off the rotor and support it without stretching the brake line.
- Remove the old brake pads from the caliper bracket.
- Apply brake cleaner to the caliper and rotor to remove dust.
- Install new brake pads in the caliper bracket, ensuring they are properly seated.

4. Inspect and Resurface/Replace Rotors

Inspection:
- Examine the rotors for grooves, cracks, or warping.
Resurfacing/Replacement:
- If the rotor is damaged beyond resurfacing, remove it by unscrewing the retaining screws (if equipped) and pulling it off the hub.
- Install new or resurfaced rotors, ensuring they are clean and free of grease.
- Reinstall the caliper over the new rotor and tighten the caliper bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and tighten the lug nuts by hand.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
Press the brake pedal several times to seat the brake pads against the rotors.
Test drive the vehicle at low speeds to ensure the noise has been resolved and brakes are functioning properly.
