Cuff Brakes
Cuff brakes are the sealing part of the piston group of the brake AKA the part that creates pressure while also sealing the piston-cylinder pair.

Cuff brakes effectively seal the piston section of the brake as well as work to seal other sections of the pistons.
By sealing the portion of the brake that has the piston group, the pressure is maintained in the area.
