I have a 67 Corvette without power brakes. I am going to be change out the incorrect master cylinder with a correct rebuilt 509 unit. I have 2 different ones. One is stainless sleeved and the other is brass sleeved The stainless one is nicer looking in that is has a much sharper 509 and DC stamp, and also the markings that are on the brake line side are also much sharper. If it matters any, the brass sleeved one has been sitting for about 6 months since it was rebuilt and the stainless one about 18 months since it was rebuilt.
I would like to use the stainless one since it looks better. I have been told that the micro-finish of the stainless steel will "file" away the rubber cup of
the piston. The brass, on the other hand, is a self-lubricating metal and
will not do this.
Any of you guys have an opinion on which one I should use? Thanks!
