The invention concerns a disk brake for vehicles that includes a turning brake disk (11) connected to a wheel (10) or to its rotation axle (14) and at least one primary brake calliper (12) connected to a non-turning part of the wheel supporting structure, and an additional brake calliper (13) angularly movable in relation to the primary brake calliper. The primary brake calliper and the additional brake calliper are managed at least to engage alternately with said disk. The additional brake calliper is activated and moves in a direction in relation to the primary brake calliper when the latter is inoperative and in the opposite direction when the additional brake calliper is in an inoperative position and the primary brake calliper is operative, to cause a progressive angular rotation of the brake disk and wheel it is associated with. |
