What is the brake calipers

.06.2021 105.5K Views

[WapCar] The brake caliper is a component that exerts force on the brake disc, the hydraulic pressure generated by the brake master cylinder finally acts on the piston inside the caliper, and after the piston expands, the brake pad is pushed to the brake disc.

 

Some readers may have questions, why can't we see where the piston is? The reason is simple. The piston of the brake caliper of ordinary family car is only on one side of the caliper, usually the side behind the brake disc, so from the outside we can only see the caliper and the brake pads fixed on the caliper.

But there are exceptions, that is, the opposing multi-piston calipers used in many high-performance cars. And "opposite" means that there are pistons on both sides of the brake disc, when braking, the pistons on both sides apply pressure in opposite directions to push the brake pads on both sides to the brake disc.
