Automobile Brake Disc and Pad Name Institution Automobile Brake Disc and Pad Car brakes are certainly one of the most important elements of an automobile. In fact, drivers consider it the most important and reliable safety device in a vehicle (Owen, 2010).
However, in special cases such as in racing cars or for people with disability, hands may be used as a means of enhancing efficiency, according to Owen (2010). It is very interesting that many people still wonders how a small peddle, in the form of a car brake is able to stop a huge car in motion with just a slight press of the brake. Similarly, it is still a mystery to many people, how it happens, though people increasingly understand the working system of a car brake. Basically, when a driver presses the brakes with the help of the legs, a force is transmitted from the driver’s foot to the brakes via a fluid. However, since the car needs a much greater force than applied by the leg to stop, the car normally multiplies the force applied by the foot. The braking system then transmits the force to the car tires and consequently the tires transmit the force to the road where the friction law applies and the car stops (Erjavec, 2008). Car brakes are of two types, namely drum and disc brakes. Drum brakes is a type of breaking system that stops a car in motion by friction, when brake shoes are pressed against the drum. Drum brakes have many components that are important for its operation. These include drum, piston, wheel cylinder, return spring, brake shoe, stud, brake pads, wheel hub, and brake lining. The existence of these components makes it easy for drivers to stop vehicles easily by applying just a little pressure on the brake pedal (Gilles, 2005). ...
