ABSTRACT:
A brake system includes separate service and emergency brake actuators. The service brake actuators are normally disengaged, and engage when supplied with pressurized fluid. The emergency brake actuators are disengaged when supplied with pressurized fluid and engage in the absence of fluid pressurization. A restricted orifice limits the rate at which pressurized fluid can be supplied to the emergency brake system. Fluid is tapped from the emergency brake system to effect service brake application. The flow of tapped fluid from the emergency brake system is regulated by an operator control to effect a controlled application of the service brake actuators. In the event of a failure in the conduit receiving tapped fluid from the emergency brake system the discharge of tapped fluid from the emergency brake actuators into the failed conduit is regulated by the operator control to effect a smooth, controlled application of the emergency brake system.
