There have two types of calipers:
Floating Calipers: Floating calipers have one or two pistons on one side of the rotor and slide on pins or bolts to allow the caliper to move in and out as the brakes are applied. Floating calipers are typically easier to install and maintain, and are commonly used on street bikes and some sport bikes.
Fixed Calipers: Fixed calipers have pistons on both sides of the rotor and are mounted rigidly to the motorcycle's fork or swingarm. Fixed calipers are typically used on high-performance motorcycles or racing bikes, as they offer better braking performance and greater control.
