I posted about this in my introduction, and was advised that maybe I should put it here. Working on a 48 Chevy 6400, and have a rear brake hanging up. I am thinking wheel cylinder. My problem is, I cant seem to find cylinders for anything over a one ton. Will that one work? This is my first foray into larger trucks, and I really enjoy driving/using it. Stopping, however, would be a bonus. Could someone maybe point me in the proper direction, maybe shoot me a part number, or a source? Something along those lines. Thanks
