Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if electrical components are involved.

2. Wheel Removal

Sub-steps:
1. Loosen lug nuts slightly on the front wheels using a lug wrench.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheels.

3. Brake Component Inspection

Sub-steps:
1. Inspect the brake rotors for warping; use a runout gauge if available.
2. Measure rotor thickness; replace if below manufacturer specifications.
3. Check brake pads for adequate thickness and even wear; replace if worn unevenly or below specifications.

4. Replace or Resurface Rotors (if necessary)

Sub-steps:
1. If rotors are warped, remove them from the hub by unscrewing the retaining screws (if equipped).
2. If resurfacing, take them to a machine shop; otherwise, install new rotors.
3. Clean the new or resurfaced rotors with brake cleaner to remove any protective oil.

5. Reassemble Components

Sub-steps:
1. Reinstall brake pads, ensuring they are properly aligned and seated.
2. Reinstall wheels and hand-tighten lug nuts.
3. Lower the vehicle and then torque lug nuts to manufacturer specifications.

6. Test and Finalize

Sub-steps:
1. Reconnect the battery if it was disconnected.
2. Start the vehicle and pump the brakes to ensure proper pad seating.
3. Take a short test drive to verify the repair.
