Hey everybody,
I got my hands on a hydroboost setup from a 1994 F450 superduty and put in in my 1988 F350. I am happy with the added performance of the braking system. However, the master cylinder from the 450 is of a larger bore than my F350. This, i believe, has caused my brake pedal to be very hard, and has very little travel. I attempted to bolt my stock master to the hydroboost, but the holes for mounting are wider on the new one and my old one doesn't fit. Is there a different master i should be using? I believe my original was a 1 1/8" bore while the 450 one is a 1 5/16" bore. Also the superduty had rear discs with a load-sensitive proportioning valve, and i am running the stock SRW drums. Any help would be greatly appreciated.
