Abstract
For braking a gyroplane rotor, a unit is proposed which comprises a disk brake equipped with a hydraulic actuator (26), which is integrated and has force amplification, as well as a mechanical transmission (54) connecting a control member such as a handle or lever (52) to the said actuator. The amplification effect is obtained by the section difference between a control piston (34) of the actuator directly connected to the mechanical transmission and a free piston (28) of the actuator by which the braking force is exerted.
