1960 Chevy Truck V8 Two Wheel Drive Manual unk miles

To whom it may concern, I have a 1957 chevy truck that I just installed new brakes, spring kits wheel cylinders, everything but drums. The new Master cylinder is a single resevior to keep it original. A friend and i keep bleeding the brakes but the pedal keeps hitting the floor not getting any resistance whatsoever. I didnt bleed the master cylinder. We have bleed each wheel maybe 7-8 times. I get a steady stream from the back wheels but the front right has alot of foam. I understand that the foam is air but shouldnt the pedal be getting a little harder to push than going to the floor as if nothing had been done? I dont understand what Im doing wrong. Please help me!!! Thank you for your time. Leo

HI there,

I would say that you have a small leak in that circuit and are sucking in air try clamping off the hose with a brake hose clamp and see if the pedal improves, if so the leak may be down stream if not up stream, try this first.
