1978 Ford F250

I have a 78 f250 and this has been the brake job from hell. I have replaced everything from front to rear and still I HAVE NO REAR BRAKES CAN ANYONE HELP? I think I might have gotten a bad proportioning valve. Does anyone know what the pressure should be for front and rear? PLEASE SOMEONE HAS TO KNOW!

Do you
have the same problem?

Rear brakes not moving at all? A porportioning valve coudl screw it up but I highly doubt it, remove them and see if you can get pressure, usually a proportioning valve that has failed will over supply the pressure.
