Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on which brakes are making noise).
Secure the vehicle with jack stands.

3. Remove Wheel Assembly

Remove the lug nuts using a socket set and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are worn down to 3mm or less, replace them.
Replace Brake Pads:
1. Remove the caliper bolts with a socket set.
2. Slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads (ensure they are oriented correctly).
5. Apply brake grease to the back of the pads to reduce noise.

5. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- Measure rotor thickness with a micrometer. If below minimum specifications or if warped, replace.
Replace Rotors:
1. Remove the caliper bracket (if applicable) and then the rotor from the hub.
2. Install new rotors, ensuring they are properly seated.
3. Torque rotor retaining screws if applicable.

6. Reassemble Components

Reattach the caliper and torque the caliper bolts to the manufacturer’s specification (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specification (usually around 76-80 ft-lbs).
