Any help would be great,

I have a 1964 Impala with four wheel drum brakes and a single master cylinder. I want to rebuild my existing brake system, but I want to switch to a dual master cylinder for saftey reasons.

I've been searching the forums, and the best I can find out is that after '67 everything had to switch over to dual M.C's.

Should I just find a dual master cylinder for a '67+ fullsized GM w/ drum brakes? OR, is there a special valve of some sort that I can use with a single M.C. and not risk complete brake failure?

Thanks in advance....

I am in the same boat as you....my 62 Pontiac has the single resevoir, which has failed a couple of times.......I want to keep the drums all the way around, but would like a dual resevoir M/C.

There would be some re-routing of brake lines, with a propotioning valve. A diagram of that would also help greatly.

If you check www.mpbrakes.com they have some brake plumbing schematics on their site. It should prove helpful....DAVE
