Im going to move the master cylinder on my 57 Chevy pu from under the floor to the firewall. What power booster would work better 8 inch, 9 inch, stock 11 inch, single or dual diphram booster? Truck has disc/drum, 11 inch discs up front and Chevelle rearend drums out back.
Just want to get the right power brake setup the first time.

What are you running for a cam ... do you have low vaccuum readings?
Do you already have Power Steering?

If the answer to the above is "yes" , then I'd definitely look at a hydroboost system. Hydroboost brake boosters use hydraulic pressure (supplied by the p/s pump) rather than a vaccuum diaphragm to provide power "assist".

My brother had a '72 Chevy truck with a fairly "lumpy" cam (low vaccuum). This combination of higher idle speed, stock torque convertor, and low vaccuum made things like parallel parking downright scary. It was fairly un-nerving to step on the brakes ... and not having much assist there.

Got power steering , mild cam with good vacuum.
Hydro booster , thats a thought.

Whats the reason for moving the brake booster? If its just to get power assist you can get units to fit on the frame in the original position. Both of these places have hydro boost units.

You can also get corvette power boosters in a frame mount.
Good luck.

Whats the 57 ? I have a used 2 different dual master cylinders under the floor with the stock pedal without a power booster, none has been very impressive yet, and im getting tired of working on it under the floor.
CPP looks to have what mite be a nice complete setup for my truck that mounts on the firewall. I was wondering what size of booster was prefered by the folks in this forum ?
