I opened up the master cylinder today and it looks really clean in there...I had some extra DOT 3 so I bleed the front brake lines and there was just a little crude that came out. Hard to tell if it's dirt or rust...either way I was glad to see that it was minimal.
I think most of the junk in that wheel cylinder made its way in there from the holes in the rubber end seals. After I took it off I took a close look I saw that both had multiple cracks.
Either way, I'm gonna go with your recommendation guys.
Thank you for the tip on the stainless lines...I will do that. I had a look at how they are routed through the frame rails and cross members and it looks like it's going to be tricky getting the old lines out and the new ones in place. It's pretty tight in some places.
