Re: arcing brake shoes

Perhaps I'm wrong but it was never my understanding that on internal expanding brakes, the shoes were to stretch or bend (flex) to give the lining full contact. I was taught that you arc the lining to give 100% contact as a dry fit before assembly. And that's the way I've always done brake relining if drums were cut oversize.

PS - an alternative to arc grinding the lining is, if using riveted linings, use of a metallic shim between the shoe and the lining. Chrysler Corp. recommended this method for many years.
