How to Tell If Brake Rotors Need to Be Replaced

If you consider the brake system of your car the first line of defense against accidents, the brake rotors control the action of the brakes. When you step on the brake pedal inside the car, the brake rotors squeeze the brake pads, which in turn makes the wheels stop safely. Knowing when to replace the brake rotors is important to the health of your brake system and the safety of your car.
Procedure to replace Brake Rotors:
1. Listen to the sound coming from your car when using the brakes during a drive. If you hear any scraping or grinding noises when you engage the brakes, inspect the rotors immediately.
2. Turn the steering wheel all the way to the right or left and park the car. Moving the wheel to the extreme will expose the brake rotor.
3. Locate the rotor behind the wheel. The rotor is shaped like a disc and runs in between the brake pads.
4. Read the writing on the rotor to find the recommended thickness from the manufacturer. The numerical measurement is the minimum thickness at which the rotor can be operated.
5. Measure the thickness of the rotor with a measuring tape. If it is lower than the number written on the rotor, it needs replacing.
