I had 5 ton on the bed of my K-7 with the smaller cyl and had no trouble stopping, MY other -7 with the bigger brakes has a GVW of 21K and I don't notice a differance.
Use whatever you can find!
again cornbinder these larger wheel cylinders I offered will NOT fit a KB-6, we went thru this before, they would not bolt on my truck that is why I got the other set,
I'm sure I could've made em work with a torch and a lot of drilling, but,,,,
the wheel cylinders I have and listed part numbers for may fit a KB-7, but he needs to check the casting #s.
so, either will work is not a correct thing to tell this guy or anyone.
Ok, But I don't know what is different between yours and mine, as I have one -7 with the smaller cyl and one -7 with the larger and both have the same shoes. I accecpt that you could not fit them, but not sure what is differnet between your set-up and mine. Could you have -5 cly? Or may be the early run of -7 used a uinque cyl with a smaller bore but otherwise identiacl to the later -7, all I know is that one uses a 11/16 bore on the small side and the other uses a 3/4" both the big sides are different also but can't remember the size.
