[DML] Re: Specs on rear caliper bolts?

["Matthew" <matthew.spittle@xxxxxxxxx>]

I'll second that.  The seal is made between the piston and the seal,
so as long as the bore doesn't have "projections" sticking out where
the piston could hit it (like you get with rust), it's not going to
interfere with its operation.  I replaced my pistons with the
stainless ones that John Hervey sells.
