Abstract

A rigid partition (18) internally delimiting a front space and a rear space in the outer casing (10) of a brake servo unit is fastened on an approximately cylindrical extension (14a) of a reinforcing plate (14) internally lining the front portion of the casing. A two-stage servo unit of simplified construction and of small dimensions, utilizable in the brake circuit of motor vehicles, is thus obtained.
