    I'm using a Eldorado master cylindar and it works great. I think the stock master cylindars work fine for most people too. You won't need the 10lb valve for the rear anymore.

    ehanks for the info i thought you needed a 10 lb valve in the rear line to keep the brakes from draggin. the front disks have a check valve so the disks do not drag and there is not one in the rear of the master cylinder because the brake shoe springs keep the brake shoes from draggin please let me know if im correct thanks /forums/images/graemlins/1zhelp.gif

    There is no set in stone sort of way to figure that part out. When I did the rear disk swap on my burb, I didn't change ANYTHING, still running all the stock brake stuff(mc/booster/prop valve/lines/etc). When I did the swap on someone elses 70 K5, a crap load of stuff had to be changed.

    So the only real way to figure out what your particular rig is going to need changed(if any)is to just do the swap and drive it and see how the brakes react.
