Abstract
A braking system including: a pressure control cylinder having a housing, a piston displaceable by activation of a drive source, and a pressure controlling chamber so that a working fluid can be supplied from the pressure controlling chamber to a brake cylinder, by displacement of the piston; and a braking pressure control device operable to control the activation of the drive source, for controlling a pressure of the working fluid in the pressure controlling chamber or in the brake cylinder. The braking-pressure control device includes: a piston-bottoming-state detecting portion operable to detect a piston-bottoming state of the pressure control cylinder and/or a possibility of occurrence of the piston-bottoming state; and a drive-source control portion operable to control the activation of the drive source on the basis of result of detection made by the piston-bottoming-state detecting portion.
