Re: Rubber plugs on '63-'64 drum brakes
Whew! Jim. For a minute there I thought you had one drum with four knockouts and I thought, wow! where did mine go wrong.
Just a caution here that I am repeating; be wary of replacement drums that do not have the knockouts, that are generic and don't have the grooves for the anti-chatter springs. I bought some from Eckler's when I did my complete brake overhaul last year (changing from Sintered Metallics to Matrix Ceramics). I was convinced (by my friends) that after 40k miles with Metallics my originals would be junk (not so). At any rate, I could not get the new brakes adjusted right with these replacement drums. I believe there is a dimensional relationship difference between the hub mounting surface and the inner braking surface, i.e. the linings would not seat in the drums, and the drum itself does not seem to fit up to the backing plate properly (close, but no cigar). I finally had to have my originals trued up (they had a minimal amount of taper and out of round, well within limits) and they work great.
