Abstract
A fluid pressure actuated brake unit has a push rod (3) axially movable in a housing (1) and a piston (2) with a wedge element (7) axially movable substantially perpendicular thereto. A wedge surface (12) on the wedge element is arranged to transmit a force from the piston to the push rod via a working roller (8) on the push rod. In order to reduce the dimensions of the wedge element (7) and to give a smooth transition from the brake application stroke to the brake operation stroke the wedge surface (12) at its end remote from the piston (2) has an edge (13) intended for coaction with the working roller (8) during the brake application stroke.
