The Bendix 231543 is a Type 30 air brake chamber diaphragm, designed as a direct-fit service part for Type 30 brake chambers. Cross-references include BW231543, BEN231543, BX231543, 745-231543, and ZAC231543, making it a widely recognized interchange. The diaphragm measures approximately 12.0 inches across its face, which is consistent with the Type 30 chamber sizing. When the existing diaphragm in a Type 30 chamber is worn or leaking, this part restores proper chamber function and brake actuation response. Available from Pro Gear and Transmission. Call us to confirm proper fit for your brake chamber configuration.
