It is a device that utilizes friction to cause a vehicle Each of the four wheels on an automobile is to decelerate and/or stop by converting kinetic equipped with a brake. Depending on the usage and energy into heat energy. Sudden braking at 100 characteristics of the car, the wheels may have disc km/h generates enough heat to raise the tempera- brakes or drum brakes. Disc brakes have the ture of two liters of water from 0°C to boiling capability to stop a car in a stable manner even at a (100°C). Brakes are relatively small compared with high speed, while drum brakes have the capability to other major automobile components, and the space stop heavier vehicles. A vehicle can be equipped where they are mounted is restricted. Complex with different combinations of disc and drum brakes. controls are required to absorb the output power of Some vehicles use disc brakes on the front and rear the engine and brake safely. Brakes are considered wheels, while others use disc brakes on the front
