<p>The invention relates to a braking corrector comprising at least one bore (11) and one piston (12) sliding within said bore and forming therein first and second pressure chambers (13, 14) separated from each other by valve means (15) carried by said piston and actuated by a push rod (16). According to the invention, the valve means comprise two bores having different diameters and mounted one behind the other and applied to respective seats (153, 156) by means of corresponding springs (153, 154). The corrector thus obtained operates much more silently and reliably.</p> |
