Abstract
A method and apparatus is disclosed for securely attaching existing central aluminum or steel adaptors for air brake actuators to existing steel service brake housings, existing steel emergency brake housings, or both without major modification to either housing or the adaptor. An annular shoulder is provided in the steel brake housing, and the aluminum adaptor is provided with a small outwardly extending annular lip. A flexible diaphragm is sandwiched between the shoulder of the steel brake and the annular lip of the adaptor. One or more C-shaped retaining pieces are then placed around the sandwiched shoulder, diaphragm and lip. A weld is then applied to connect the C-shaped steel piece to the steel-housing, thereby holding the aluminum or steel adaptor and diaphragm securely in place.
