<p>A dual braking system for industrial vehicles of the type in which only two wheels on a common axis are normally braked, and which includes a hydraulic disc brake system in which each wheel has two separate sets of brake cylinders which are connected by separate lines to a common master cylinder. In case of failure of one of the supply lines, a valve interposed between the master cylinder and the brake cylinders closes off the failed line in response to the pressure imbalance caused by the failure. The movable element of the valve is also adapted to close a switch which can be connected in a suitable indicator circuit to warn the vehicle operator that a failure has occurred. According to another aspect of the invention, a floating brake disc is disclosed.</p> |
