Either will work and unless you run heavy all the time will stop just fine. 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.

At this time I really am not doing a full correct resto just trying to get it functional and working. That being said I don not know if I want to cut and adapt to much if not needed. Although looking at 650 price I might get real creative. Being the cheapskate that I am I am pondering doing the resleeve myself if I can find kits. Will post again when get rears off and know what I have. Thanks again for the ideas.


Hi mtjohn, I was just commenting on the Pat Walsh's offer to me of $650 a piece to find em for me,

I found em myself,
if these wheel cylinders I listed the part numbers for will work for you $125 a piece? cheaper than having them sleeved, I know that.
check your casting #s.
if you have the smaller one like I did, then can't help you,
Gentle Men! you can't fight in here! This is the war room!
