Riveting the linings on brake shoes on hydraulic brake assemblies was historically the industry standard, while electric brake assemblies typically have the pads glued or bonded into place. All Demco could tell me is that they rivet all of their brake linings.

I also spoke with folks at Dexter. I was told that in the past the adhesives used to bond the linings on the shoes were unable to withstand harsh marine environments. If water should penetrate between the shoe and the lining, rust can occur, which would cause the lining to separate from the brake shoe. This made riveting the lining a superior method of attachment for brake linings (at that time) used in marine environments. Dexter tells me that they now bond all their brake linings, which leads me to believe that the adhesives used have improved over the years, as Dexter would not use this method if it was not 100 percent reliable.
