Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

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

3. Inspect Brake Components

Tools Required: Torque wrench, caliper tool
Sub-steps:
1. Inspect brake rotors for warping by measuring thickness with a micrometer.
2. Check for any scoring or grooves on the rotor surface.
3. Remove the brake caliper using a socket wrench, and inspect the brake pads for even wear and adequate thickness.
4. If pads are worn unevenly or below the minimum thickness, replace them.

4. Replace Rotors (if necessary)

Tools Required: Torque wrench, socket set
Sub-steps:
1. If rotors are warped or damaged, remove them by unscrewing the retaining screws or bolts.
2. Install new rotors, ensuring they are properly aligned and seated.
3. Torque the rotor bolts to the manufacturer's specifications (usually around 70-90 Nm).

5. Reassemble and Test

Tools Required: Torque wrench, lug wrench
Sub-steps:
1. Reattach the brake caliper and ensure it is secured properly.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and tighten the lug nuts to the correct torque specification.
4. Reconnect the battery.
