Abstract
A rail vehicle braking system includes a service brake () having a movable piston () delimiting with a body () of the system a service brake chamber () supplied by a first source, and a parking brake () having a blocking device () having a position in which it immobilizes the piston in a position, and a movable actuating device () delimiting with the body a parking brake chamber () supplied by a second source and having a stable position in which it holds the blocking device in its position; the service chamber, when the actuating device is in its stable position, being supplied by the second source of which the pressure is greater than that of the first source in order to apply a greater braking force than the force applied when the piston is in its position.
