I'm building a car for a friend and he has to have a stock brake system. What master cylinder do I need so he can run without a vacuum booster?? It will have disks all the way around too.

Use the one you've got! Just take the booster off and take the rod out of it and bolt the M?C back on. I learned that one right here on the forum! Don't believe me? Do what I did-go to the AutoZone and look up the pn for both a power boosted mc and a non power mc. You just might save yourself some $! You may want to change the porportioning valve tho-use one off a car with discs all around. I've heard there were some caddys with stock adjustable porportioning valves( internal spring change), but I don't know which ones. Maybe a trip to the pic-n-pay will solve that mystery.

The MC from a power unit normally has a 1-1/8" piston in it, the MC from a manual unit has a 1" piston. If you try to use the MC from a power unit you will have a really stiff brake pedal. A manual MC is pretty cheap at the parts store.

If you will move the brake rod to the top hole on the brake pedal arm your brakes will not be hard. It took me 2 seasons to learn about that. I know on metric cars it has 2 holes, if your car doesn't have the extra hole just drill a new one about an inch and a quarter higher. It works.

Well Tornado, yours does-after you install them! Find a Camaro or Firebird with stock discs and swap the rotors and calipers for the drum set-up you've got now! Should be a bolt-off, bolt-on swap.
