A key part of your vehicle's brake system, rotors are the large metal discs that are inside of each wheel. Found on disc brakes, the rotor is attached to the wheel by the vehicle's axle. Depending on the design of your hubcaps, they may be visible.

The term “brake,” as used in modern sheet metal fabrication, comes from the Middle English verb breken, or break, which meant to bend, change direction, or deflect. You could also “break” when you drew back the string of a bow to shoot an arrow. You could even break a beam of light by deflecting it with a mirror.

Basic Components A press brake is mainly made up of c-shaped frames, a top die or punch, a bottom die, and a hydraulic system. The flow of fluid that moves the top die is controlled by the hydraulic system. This system has tanks, pumps, motors, valves, and pipes. They all work together to move the top die.

Once you have the desired break lines. You're going to line them up by eye with the punch tip as it comes down and bends the first bend.
