<p>In a normal state, a braking control section (11) performs normal control wherein the hydraulic pressure that is made to be generated in a primary hydraulic pressure chamber (26) and a secondary hydraulic pressure chamber (24) is cut off with respect to a slave cylinder (S/C), and wherein a wheel cylinder (4a) etc. are made to operate by means of the hydraulic pressure that is made to be generated in a first hydraulic pressure chamber (66) and a second hydraulic pressure chamber (64). In an abnormal state, the braking control section (11) performs operations wherein the wheel cylinder (4a) etc. are made to operate in such a way that the hydraulic pressure that is made to be generated in the primary hydraulic pressure chamber (26) and the secondary hydraulic pressure chamber (24) is not cut off with respect to the slave cylinder, wherein a cutoff means (47) is made to cut off delivery of brake fluid from the secondary hydraulic pressure chamber (24) to a stroke simulator (S/S), and wherein when leakage of brake fluid is detected, normal control is performed with respect the slave cylinder (S/C), and the cutoff means (47) is made to cut off delivery of brake fluid. Thus provided is a braking device such that even if brake fluid leaks, it is possible to prevent a pedal stroke (full stroke) from increasing.</p> |
