So I traded my 3rd gen 5.9leaker for a pretty good solid 2nd gen 12v. No blow by and 280xxxkm 5spd nv4500 with a Southbend clutch. My problem is the brakes are so hard and I was told it could be a master cylinder or brake booster. Also I noticed that my intake elbow is making contact with the master cylinder and it looks off. But how do I know for sure? Also another weird thing is that for a 1996 it has a VE pump. Bottom line is. How do I tell it’s my MC or my brake booster. Thanks in advance.
