Hi, can anyone tell what the acceptable run out for a speed 25 brake drum, please? I measured one of mine at +/-10thou and replaced it with a good 2nd hand one which showed +/-4thou. The method is shown below (from a transit van forum!). [attachment=1:ryskfrbu]<!-- ia1 -->brake drum run out.JPG<!-- ia1 -->[/attachment:ryskfrbu] Next step is to make an adaptor to allow me to skim them myself on my lathe (yes it is big enough with gap piece removed). I assume there must be a minimum thickness / maximum diameter specification as well. thanks Dave Posted by DaveT 16/02/2015 13:00:15
