How disc brakes work

The working characteristics of disc brakes: disc brakes use brake calipers to clamp the brake disc that rotates with the wheel to brake the car. Disc brakes are generally classified by the number of pistons in the caliper. It can also be divided into the form that the caliper body is fixed on the bracket, which can be divided into two types: fixed and floating.

The floating clamp-type brake cylinder is mounted on one side relative to the brake disc. In addition to the displacement of the cylinder piston, the clamp can also move axially. The fixed-clamp brake cylinder is located on both sides with respect to the brake disc. Only the cylinder of the cylinder can move, and the braking force is large.

Because the brake disc is exposed to the air, it is easy to dissipate heat, so the braking efficiency is superior at high speed braking. The dirt, dust, or water stuck to the brake can be thrown off by the centrifugal action of the brake disc or scraped off by the brake caliper, which will not affect the braking effect. The brake disc is usually double-layered with cooling in the middle Sheet can further improve the heat dissipation effect.
