Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake grease, torque wrench
Sub-steps:
1. Remove the caliper bolts and carefully take off the caliper.
2. Slide out the old brake pads and inspect for wear; replace if below the manufacturer's specifications.
3. Apply brake grease to the back of the new brake pads.
4. Install the new brake pads into the caliper bracket.

4. Check and Resurface or Replace Rotors

Tools Required: Brake rotor gauge, impact wrench (if necessary)
Sub-steps:
1. Measure the thickness of the rotors using a brake rotor gauge.
2. If rotors are below specification or severely damaged, remove them by unbolting from the hub.
3. Resurface rotors if they are within acceptable limits, or replace with new rotors if damaged.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper and torque the bolts to the manufacturer's specifications.
2. Reinstall the wheel and torque the lug nuts in a crisscross pattern.
3. Reconnect the battery terminal and lower the vehicle.
4. Test the brake system by gently applying brakes to ensure proper function.
