Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted using jack stands.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel that needs inspection.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Check Condition: Examine brake pads for wear; they should be at least 1/4 inch thick.
Replace if Worn: If pads are worn down:
- Remove brake caliper bolts using a socket wrench.
- Slide the caliper off the rotor and secure it to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they fit snugly.

4. Inspect and Resurface or Replace Rotors

Check Rotors: Measure rotor thickness with a micrometer and look for grooves or warping.
Resurface or Replace: If rotors are below minimum thickness or severely damaged:
- Use a rotor puller if necessary to remove rotors from the hub.
- Resurface if within specs or replace with new rotors.
- Install new rotors by aligning them with the hub and securing any retaining screws.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reattach the wheel, hand-tightening the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value (usually 75-80 ft-lbs).
Reconnect the battery.
