Disc brakes use a flat, disk-shaped metal rotor that spins with the wheel. When the brakes are applied, a caliper squeezes the brake pads against the disc (just as you would stop a spinning disc by squeezing it between your fingers), slowing the wheel.
Disc brakes use the same principle as bicycle handbrakes, but on a bike the brake pads press against the wheel itself. On a car, the disc is part of the hub to which the wheel is mounted. The disc, technically called a rotor, is clearly visible through spoked wheels.Disc brakes generate amazing stopping power even in the worst conditions because they utilize rotors (photo) attached to the wheel hubs, and calipers attached to the frame containing specially designed pads
The main components of a disc brake are:
- The brake pads
- The caliper, which contains a piston
- The rotor, which is mounted to the hub
How Disc Brakes Work?
On a disc brake, the fluid from the master cylinder is forced into a caliper where it presses against a piston. The piston, in turn, squeezes two brake pads against the disc (rotor) which is attached to the wheel, forcing it to slow down or stop.
This process is similar to a bicycle brake where two rubber pads rub against the wheel rim to create stopping friction.
Why do disc brake have holes in them?
Due to following reasons :-
>These holes significantly increasing the grab or friction of the brake caliper pads.
>Reduce the weight of whole assembly.
>For proper heat dissipation generated during braking.
>The holes are spaced in such a way that the calipers used in the brake wear out uniformly, to ensure maximum longevity.
it's good information. thank you
