Re: [FWDLK] Maximum Brake Drum Diameter

[Wayne Graefen <WGraefen@xxxxxxxxxxxxxx>]

Ron,

Parts houses and brake repair shops used to have books which specified how
far drums could be turned over sized.  The spec for the vast majority of
drums was .060".  Some as much as .085".  Some GM and off-brand or foreign
cars were around .040".
Your shop is telling you yours are .010" oversize which is EXCELLENT!  You
have nothing to worry about!

Hi Gang -

I have two sets of 11 x 2 1/2" front drums for my 59 Dodge.  I'm trying to
find out if they still have enough metal on them to be turned.  But I've
been unsuccessful in finding the maximum diameter that the drums can be
before they are no good.  I had a brake shop measure them and they are all
in the 10+ range, whatever that means.  Does anyone out there have the info
I need to make this determination ?  Are my drums still turnable, or are
they junk and should be discarded ?

Thanks,

Ron
