My neighbor recently bought a 40 Ford Deluxe coupe that was built in the 90's. It has been converted to front manual disc brakes on a dropped axle, the guy he got it from also bought it that way so he doesn't know what components were used. The brakes have never been right as the pedal is soft despite bleeding over and over. The PO tried different master cylinders, the one on it now is off an 80's Camaro with a 1 1/4 inch bore. It has a proportion valve that is not adjustable. I have searched the H.A.M.B. but so far with no luck to tell him what to try next other than find a master cyl. with a smaller bore, like 1 inch. I have driven the car and he is right, it gets scary trying to get it stopped. He is going nuts as he wants to drive it as a DD a lot but he is afraid to. Anyone got any ideas?
