Abstract

A hydraulic-reaction master cylinder (2) having a working chamber (12) in which slides a hollow main piston (13) with a bore (130) therein which retains a reaction piston (14) to define a reaction chamber (15). The reaction chamber (15) has an annular shape and communicates with the working chamber (12) through at least one non-return valve (22) or an axial passage (23). The axial passage (23) is closed off selectively an axial stub (141) that extends from the reaction piston (14).
