Re: [Chrysler300] 300G Rear Brake Backing Plates



On my 62, a genius/artist welded larger nuts over the existing adjusting studies.I think there is a size with slides right over leaving some cleanse for welding. Mine retain t he beautiful weld bead . He did such a nice job, the arrows still show on the heads of the original adjusting studs. I used some roil and got mine freed up first, The much larger nut makes it easier to adjust also.

( you can do that once cam is free to restore function, if that is close in goal, but to do right have to be off the car ?)   . I was looking at a way to fix. It looks like you could press a 1/2 20 nut in a big hydraulic press onto stud with some finessing . Hole in backing plate would have to be made larger to pass it . Have not looked at that part yet . Then weld center . Ground weld  clamp to nut not plate keep current out of cam . Trying to understand these brakes better . Grossly inept things " rebuilding" them cause problems . More coming !  First reaction on some new info --/ never turn drums + keep old shoes if 1/2 left . Circular wear scratches in drums hurt nothing . I think at times we cause ourselves problems with new shoes unless arc ground shoes .  Turning the drums requires that . But those machines  are all gone around here due to asbestos dust . Better old worn -in shoes rebuild cylinders etc that fit drums right than all new that are a different incorrect diameter . My 02 . Especially if not driven a lot . 
> Spec is .003- .005 gap all along shoe. No way if you turn drums . 5000 miles of grabbing pulling and grief  can result... Shoes touch in a patch instead of whole length .  As well as rapidly dropping pedal . 
> Not sure the 7 ft lb minimum force to turn is right either . If oiled to stop rust might be less . As near as i can tell if cam slips by itself it will tighten shoe . The way forces are . ( balanced by retainer when resting  no net force on cam ) anyone have experience with shoes that tightened by themselves?
