ABSTRACT:
A thrust device of the kind in which an axial thrust is produced by relative angular movement between two substantially parallel thrust plates between which balls or rollers co-operate with inclined ramp surfaces, for use in a spreading type disc brake for example. Deformable means are provided between a ramp member and a thrust plate carrying it to allow the ramp member to be displaced axially on initial actuation of the device to even out the load between the balls or rollers for subsequent actuations. The deformable means is provided by having a localized area of contact between the wedge member and its thrust plate.
