IMPROVED HYDRAULIC BRAKE ARRANGEMENT FOR AN OFF-ROAD VEHICLE

Hydraulic brake arrangement (1) for controlling a brake (3) of a vehicle, comprising a pump (4) configured to suck fluid from a source of fluid (2) towards brake (3) via a conduit (5) and a first, a second and a third valves (7, 8, 9) fluidly interposed in series on conduit (5),first valve (7) being an electro-actuated valve configured to assume a first position into which it allows passage of fluid from pump (4) towards said valve (8) and a second position into which it allows passage of fluid from second valve (8) to a discharge (10),second valve (8) being an electro-actuated valve configured to assume a first position into which it allows passage of fluid between first and third valves (7, 9) and a second position into which it allows passage of fluid from second valve (8) to a discharge (10),third valve (9) being an electro-actuated bistable valve configured to assume a first position into which it allows passage of fluid between second valve (8) and brake (3) and a second position into which it allows passage of fluid only from second valve (8) to brake (3).
