L'unité de maître-cylindre (20) est formée par la combinaison d'un mécanisme de levier et d'un maître-cylindre hydraulique (21). Le mécanisme de levier comporte un premier levier rotatif (41), un second levier rotatif (42), un percuteur (43) et un levier d'égalisateur (44). Dans le maître-cylindre hydraulique (21), un circlip (25) qui régule la limite vers l'arrière d'un piston (22) est fixé à l'ouverture d'un trou de cylindre (21b) dans lequel est introduit le piston (22). L'unité de maître-cylindre (20) est disposée dans un auvent (51) du véhicule à guidon (50).
