Solution

1. Preparation

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

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper by unscrewing the caliper bolts with a socket set.
- Slide the caliper off the rotor, ensuring not to stretch the brake line.
- Check the brake pads for thickness; if they are below 3mm, replace them.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads in the bracket, ensuring they fit snugly.
- Apply brake grease to the backing of the brake pads to prevent noise.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check the rotor surface for grooves or uneven wear. If damaged, replace the rotor.
Replace Rotors:
- Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Install the new rotor, ensuring it is flush against the hub.

6. Reassemble and Test

Reattach the caliper and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 76 ft-lbs).
Test the brake system by pressing the brake pedal a few times to seat the pads.
