A hydraulic braking arrangement for controlling front and rear brakes of an off-road vehicle, includes a power brake valve fluidly interposed between rear brakes and a first source of fluid in pressure of vehicle. The power brake valve is configured to selectively allow passage of fluid coming from first source to rear brakes. The power brake valve is further configured to provide at least a hydraulic signal configured to control a relay valve fluidly interposed between front brakes and a second source of fluid in pressure of the vehicle and being configured to selectively allow passage of fluid coming from second source to front brakes in function of the at least one hydraulic signal.
