All questions are concerning my '65 Malibu:
Here goes, I currently have power brakes on my '65, but it is a single circuit master cylinder. Can I just bolt on a later master cylinder to my booster to upgrade to dual circut? If so what year Master Cylinder should I use for a disc/drum setup? Also, I think I found a good rear disc setup cheap. I am planning on putting disc brakes on the front of my Malibu, If I end up with disc/disc, will I need a proportioning valve still? Thanks in advance for the help Charles www.65ss.com
