If damaged, replace the affected tire(s).

3. Examine Brake Components

Tools Required: Jack, jack stands, lug wrench
Raise the vehicle and remove the wheel to access the brake assembly.
Inspect brake pads for wear; if they are worn down to the backing plate, replace them.
Check the brake calipers for signs of overheating and ensure they are functioning properly.
Replace any damaged or worn brake components.
