Abstract
A sealed vehicle brake actuator having a housing divided into a first chamber and a second chamber by a movable member such as a diaphragm. The housing comprises a first and second portion joined with the diaphragm therebetween to seal the portions to one another and mount the diaphragm. The joint is formed by deforming at least a part of the first portion into a groove formed in the second portion with the diaphragm pinched between first and second housing portions. The deforming of a part of the first portion into the groove can be accomplished by deforming the wall edge of the first portion, continuously or discretely, into the groove, preferably by rolling. Alternatively, the sidewall of the first portion overlying the groove can be deformed into the groove by rolling the first portion, continuously or discretely, or by discretely punching the sidewall.
