Abstract
In an enabled mode of a first-fill device, if a fluid pressure in a first pressurizing chamber is lower than a predetermined value, a working fluid can be supplied to a brake cylinder from both the first pressurizing chamber and a second pressurizing chamber. If the fluid pressure in the first pressurizing chamber becomes higher than the predetermined value, the working fluid can be supplied only from the second pressurizing chamber. On the other hand, in a disabled mode of the first fill device, no matter how high the fluid pressure in the first pressurizing chamber is, the working fluid is supplied to the brake cylinder only from the second pressurizing chamber or supplied from both the first pressurizing chamber and the second pressurizing chamber.
