A car rotor is a part of a car’s braking system. It is roughly shaped like a flat-bottomed bowl with a wide lip at the top. The calipers and pads of the brake press against the sides of the rotor when the brake is applied, making friction to stop the vehicle. The way the rotor is designed allows the heat created by this process to be evenly dispersed throughout the braking system so it does not get overheated. Normal use of the brakes will eventually create wear on the various parts of the brake system, and if they are not checked and replaced regularly, it can get damaged. If this damage is not addressed, it can graduate to the point where the brakes are ineffective and might totally fail, putting the vehicle and its occupants in danger. However, there are easy ways to tell if a rotor is bad so services to correct the problem may be initiated.
