Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

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

3. Remove the Wheel

Using a lug wrench, loosen and remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and hang it securely without stressing the brake line.
- Check the thickness of the brake pads; if they are worn below the manufacturer’s specifications (usually 3mm or less), they need replacement.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are compatible with the vehicle model.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for any deep grooves or warping on the rotor surface.
- Measure rotor thickness; if below the minimum tolerance, replace the rotors.
Replace Rotors:
- Remove the caliper bracket bolts and detach the bracket.
- Slide off the old rotor from the hub.
- Install the new rotor, ensuring it fits securely on the hub.

6. Reassemble and Lower the Vehicle

Reattach the caliper bracket and tighten the bolts to the manufacturer's torque specifications (usually around 20-30 ft-lbs).
Reinstall the caliper over the new pads and secure it with the caliper bolts.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then tighten the lug nuts to the manufacturer’s specifications (typically 76-100 ft-lbs).
