Thanks for the clarification! As far as I know they were all drilled. I could see honing the pilot bearing bore being skipped on automatic equipped vehicles. I thought it may not hurt to ask in the interest of the OP, but I would like to know myself. If it needs to be honed, would that be a machine shop job with either a fixed hone or a small diameter boring bar or could a person get by with a floating brake cylinder hone? I know it would have to be measured but at what point of material removal would you consider it a do at home vs. a sending it to the machine shop?
