Product Overview
The WA12964 Type 30/30 brake chamber is a long stroke spring brake actuator used in heavy-duty truck and trailer air brake systems.
This chamber features a 3" long stroke design with a welded clevis, providing increased braking force and improved slack adjuster performance compared to standard stroke chambers. It is commonly used in S-cam brake systems for both service braking and spring-applied parking/emergency braking.
Built as an aftermarket replacement for Bendix K193948BXW, this unit matches key specifications including 3/8"-18 NPTF air ports, 2.25" push rod length, and welded clevis configuration.
