What is a Brake Rotor?
A brake rotor is popularly known as a brake disc. It is a shape or surface that is round and flat in appearance. As it is shown in the image below that fine flat surface is the disc. This rotor or disc spins with the wheel as the car moves forward and backward.
Function of a Disc
Brake rotors are necessary component in the braking system that stops the vehicle. Brake rotors are what the vehicle’s brake pads clamp down on to stop the wheels from spinning. Brake rotors are just as important to stopping the vehicle as the brake pads are.
In a disc brake system most vehicles have disc brakes only on the front wheels, though newer vehicles may have disc brakes on all four wheels. A disc brake is a type of brake that uses calipers. As it is shown above, the caliper is the one attached to the side of the disc. It is in the caliper that the brake pads are attached and the disc will be in between the pads. The caliper will squeeze the pair of pads against a disc or “rotor” to create friction.
How is it done? With disc brakes, the fluid from the master cylinder forces into a caliper where it presses against a piston. The piston squeezes two brake pads on a disc rotor attached to the wheel. This forces the wheel to slow down and stop.
The Brake Pads
These pads are installed by pairs in the caliper. In between the pads is the brake disc. When the inner pad is pushed by the piston both the pads will squeeze the disc to halt the car.
