Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly before raising the car.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect Brake Components

Visually inspect brake pads for thickness and wear. Replace if less than 3mm.
Check the rotors for scoring. If damaged, they should be resurfaced or replaced.
Inspect the brake calipers for any signs of wear or sticking.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set.
Slide the caliper off the rotor and support it without stretching the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly aligned.

5. Replace or Resurface Rotors (if necessary)

If the rotors are scored, remove them by unscrewing any retaining screws.
If resurfacing, take them to a machine shop. If replacing, install new rotors.
Torque rotor retaining screws to the manufacturer's specifications.

6. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and tighten lug nuts in a star pattern.

7. Final Checks

Lower the vehicle and remove jack stands.
Pump the brake pedal to seat the new pads.
Test drive the vehicle to ensure the noise is resolved.
