Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
Replace Brake Pads:
- Install new brake pads into the caliper bracket, ensuring they are correctly oriented.
- Apply brake grease to the backing of the pads to reduce noise and prevent sticking.

4. Check and Replace Brake Rotors (if necessary)

Inspect Rotors:
- If the rotors are scored or below the minimum thickness, they should be replaced.
Replace Rotors:
- Remove the caliper bracket using a socket set.
- Slide the old rotor off the hub and install the new rotor.
Reinstall Caliper:
- Reattach the caliper over the new pads and rotor.
- Torque the caliper bolts to the manufacturer's specifications (typically around 20-25 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and lug nuts, and lower the vehicle.
Reconnect the battery and perform a brake fluid check.
Pump the brakes to seat the pads before taking the vehicle for a test drive.
