The Wabco Tristop D T30/3, part number 9253921720, is a combination spring brake and service brake chamber in the Tristop D series. The T30/3 designation identifies this as a Type 30 spring brake actuator with a Type 3 service side, a common configuration in heavy-duty air brake systems on trucks and trailers. Wabco Tristop units integrate both the service and spring brake functions in a single compact housing, simplifying installation and reducing the number of brake system connections at the axle end.
