I recently purchased replacement brake adjusters for the rear of my 1 1/2 ton. They are the disc type with the bolt head. My question is: How were the discs fastened to the flat on the bolt? Was the end of the bolt just peened over the disc, or how does it stay on?
Yes they originally were peened over to attach, not the most durable fastening technique. They can be MIG welded on, just try to do it without building up enough heat to damage the spring. I welded mine similar to the way you would weld sheet metal, a little spot here, let cool; a little spot there, let cool. I would imagine picking a good cool/cold day in WI would work well in dissipating heat as well.
