Abstract

L’invention concerne un système hydraulique (1) d’assistance au freinage pour véhicule automobile via un maître-cylindre (12) présentant une première chambre (121) et une deuxième chambre (122) logeant chacune un premier fluide hydraulique. Dans le but de prévenir des défaillances électriques du système hydraulique (1), le système hydraulique (1) comporte un dispositif de sécurité (19) qui, lors d’une telle défaillance, établit une liaison fluidique entre, d’une part, des deuxièmes conduits reliant la deuxième chambre (122) du maître-cylindre (12) à deux premiers récepteurs de freinage (10) et, d’autre part, des premiers conduits reliant la première chambre (121) du maître-cylindre (12) à deux deuxièmes récepteurs de freinage (10), afin de permettre un transfert et/ou un équilibrage de premier fluide hydraulique entre eux.
