Master cylinder having a body equipped with a bore housing at least one piston operated by the driver. The piston, which forms a slide valve, separates the feed chamber connected to the brake fluid reservoir from a pressure chamber connected to the brake circuits. The feed chamber is bordered by a groove (152) accommodating a seal (180) separating it from the outside, with respect to the surface of the piston (130). The seal (180) has a cross section in the shape of a lying-down U, one leg (181) of which is pressed against the closed end (152a) of the groove (152) and its two adjacent wall (152b, 152c), the other leg (182) providing sealing by pressing against the piston (130). The end (184) of at least one of the two legs (181, 182) has a flat surface intended to press against the side (152c) of the groove (152). |
