The invention relates to a braking device, constituted by a housing in which is housed a brake disc fixed in rotation with respect to the housing, a shaft mounted to rotate, a rotary brake disc, fast with the shaft, a first jack, constituting a pressurized fluid braking control member, and a second jack distinct and independent of the first jack, which defines, inside the housing, a brake-release chamber, to which is coupled an elastic safety braking member, the mobile element of the first jack and the piston of the second jack being stacked axially in that order from only one of the two ends of the alternate stack of the fixed and rotary brake discs. The mobile elements of the two jacks are each at least partly contained in the brake-release chamber which, furthermore, contains each fixed brake disc and 1 or each rotary brake disc. One application of the present invention is a multiple-effect brake of satisfactory compactness.
