Abstract
A braking circuit including at least an auxiliary right valve () and an auxiliary left valve () suitable to allow braking on both sides, right and left of a vehicle, when this is required, but allowing to apply a pressure braking only on one of the two sides, right or left, when this is required to provide a steering function, characterized in that the circuit further comprises a master valve () having two positions: a first position when the vehicle has a velocity under a threshold wherein separate and selective right or left braking is authorized and a second position when the vehicle has a velocity above said threshold wherein said master valve () connects both a right braking line () and a left braking line () to an output braking line () so that if a braking is requested both right braking line () and left braking line () are under pressure and selective right or left braking is forbidden.
