ABSTRACT:
A brake actuator includes an inelastically deformed separate clamp band holding the brake actuator housing portions together. The actuator is formed by cutting the clamp band from a roll of thin stainless steel. The cut portions are formed to have an L shaped section. The short L end is then placed on one of the flanges of the brake actuator housing members. The other end of the clamp band is then deformed inwardly to secure the brake actuator housings together. The invention results in a relatively low cost clamp band. The clamp band has particular application on the service side of the spring brake actuator, although it would also be useful on the emergency side.
