Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, wheel chocks.
Safety Warnings: Disconnect the battery before working on the braking system. Allow the brake components to cool if they have been used recently.

2. Brake Pad Replacement (if needed)

Lift the Vehicle:
- Use the jack to lift the vehicle and secure it with jack stands.
Remove the Wheel:
- Use a socket set to remove the lug nuts and take off the wheel.
Remove Caliper:
- Unbolt the caliper from the bracket using the appropriate socket.
- Carefully support the caliper to avoid stress on the brake line.
Remove Old Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Inspect and Clean Components:
- Inspect the rotor for any issues; clean the rotor surface with brake cleaner.
- Check the caliper for function; clean the caliper slide pins and apply grease if necessary.
Install New Brake Pads:
- Insert new brake pads into the caliper bracket.
Reinstall Caliper and Wheel:
- Reattach the caliper and torque bolts to the manufacturer’s specification (typically 20-30 ft-lbs).
- Reinstall the wheel and torque lug nuts to specification (typically 75-85 ft-lbs).

3. Rotor Replacement (if needed)

Follow the steps above for brake pad replacement.
Remove Rotor:
- Unbolt the rotor from the hub (if applicable) or remove it by sliding it off the hub.
Install New Rotor:
- Place the new rotor onto the hub and secure it with bolts.
