  • Power-manual brake system
    Patent number: 4444438
    Abstract: A vehicle brake system that is selectively power or manually operable. A novel isolation valve (2) isolates the manual part (4,5,8) of the system from the power part (10,18) when the latter is inoperative. This prevents the flow of manually manipulated fluid to the inactive power part of the system, with the consequent needless loss of fluid pressure and braking effort.
