Abstract
A dual piston brake arrangement for selective holding engagement of a rotatable member of a drive train includes a support structure, a service brake piston axially reciprocably and nonrotatably mounted within the support structure with a fluid passage therethrough, a fluid actuator for biasing the service brake piston toward a brake holding position, a secondary brake piston axially reciprocably and nonrotatably mounted within the support structure and in substantially radially aligned relation within the service brake piston for selective telescopic movement from an abutting to a separated condition therefrom, and a fluid circulating system for delivering a fluid radially outwardly adjacent the rotatable member and the service brake piston for cooling thereof and subsequently along an egress path including flow of the fluid through the fluid passage in the service brake piston.
