I had the selling dealer replace the front brake disc, calipers, lines and pads before they transported it from PA to KY. So I didn't really know how any of this was done and what to expect. Taking it all apart was a lot easier than most car brakes I've worked on. Sometimes there is an advantage to working on "big" parts.
Steven, those shims were there for two reasons, neither reason was a good one.
The first reason was to keep the pads from squeaking
, obviously spectacularly unsuccessful. They were attached to the pads when new, the squeaking sound is the pad vibrating in the caliper.
The second reason is to help keep heat away from the caliper, that is why there were two on the inboard pad, nearest the piston, which is susceptible to heat damage. It didn't work well for that, either. If you want to replace the pads, I recommend Wagner Thermo-Quiet pads, they have a different composition to not squeak, and reduce heat transfer and brake dust. They are not cheap, but not horrible, either. The last price I got for a set of these was around $60.00 for a set on a dually pickup, the pads for the MH should be about the same. Out of 200+ brake jobs, I had two come back for brake noise, neither turned out to be the pads.
