The rotor brake assembly is a piston actuated, hydraulically operated braking device for stopping the helicopter rotor and preventing rotation of the rotor.

Each rotor brake assembly is composed of a brake disc, friction surfaces, and two pistons opposing against the brake disc. The pistons will have spring retracts for positive clearance when the brake is not operational.
The brake assembly uses a split-brake cylinder with a single inlet port. Wear indicator pins provide a visual or tactile indication of usable lining remaining. The disc, which is a wear component, is not part of the rotor brake assembly.
