1964 Brake Improvement Tips

[BigClay]

Hi everyone. Just wanted to share this: Several years ago I decided to install Disc Brakes on my ‘64 Convertible. They worked a little better than the drums. A year went by and I installed Rear Discs. They worked “better” but I still wasn’t impressed. I then installed a Dual Master Cylinder and converted to a “dual system”, but brakes were so-so…….hard pedal, but no stopping power.
I tested pressures to all four wheels and was getting only 600psi. (Discs need 1000). To shorten this long story: I just installed a Vacuum Booster Pump. (Bought it from Jegs. Simple installation) Now I have the brakes I’ve been looking for!
I can even “lock them up”! Never possible before. For those of you that think I am running “too radical of a camshaft”, I have a Cobra Jet 390 grind, but only getting 13” of vacuum. Discs need more!

Congrat's on the changes. Sounds great! I'm curious how you got the dual master cylinder to fit. Can you send pictures? I've never found a good way to do this without cutting into the inner fender, removing the shock tower brace, or retrofitting a Toyota or other master cylinder or booster. What am I missing? Thanks.

Use a Tuff Stuff Performance 2131NB-2 booster and dual master.

Modify the operating end by trimming it. OE booster compared to new:
