Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Loosen the lug nuts using a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect Braking Components

Brake Pads:
- Remove the caliper bolts using a socket set and slide the caliper off.
- Inspect the brake pads for wear; replace if the thickness is less than 3mm.
Brake Rotors:
- Check the rotors for grooves, warping, or excessive wear. Replace if necessary.
Calipers:
- Check for any signs of corrosion or malfunction. Replace if they do not operate smoothly.

4. Replace Components

If pads or rotors are worn:
- Remove the old pads and install new ones, ensuring they are correctly aligned.
- If replacing rotors, remove the old rotor and install the new one, securing it with the appropriate torque specifications (typically around 90-100 ft-lbs for rotor screws).
- Reinstall the caliper and secure it with the caliper bolts.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).
Reconnect the negative battery terminal.
Perform a brake test to ensure functionality and listen for any remaining noise.
