Solution

1. Preparation

Tools Required: Wheel chocks, jack, jack stands, dial indicator, torque wrench, brake cleaner, and a basic tool set.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

2. Lift the Vehicle

Sub-steps:
1. Loosen lug nuts slightly (do not remove).
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel to access the brake components.

3. Inspect Brake Components

Sub-steps:
1. Visually inspect the brake rotors for signs of warping or scoring.
2. Measure rotor thickness using a micrometer; replace if below specifications.
3. Check brake pads for thickness; replace if worn beyond minimum limits.
4. Clean the rotor surface with brake cleaner to remove any debris.

4. Replace Components (if necessary)

Sub-steps:
1. If rotors are warped, remove caliper bolts and carefully lift the caliper off the rotor.
2. Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
3. Install new rotors by reversing the removal process; torque retaining screws to manufacturer specifications.
4. Replace brake pads by removing the caliper bracket, replacing the pads, and reassembling.

5. Reassemble and Lower the Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and remove the jack.
3. Tighten lug nuts to the manufacturer's specifications using a torque wrench.
