disk brakes

[fink]

Just converted my 71 k-5 to one ton, w/ 4 wheel disk brakes, I did a search but didnt find a definate answer. I eleminated the stock proportioning valve and plumbed in a wilwood prop. valve for the rear. Before I go further do I need a 4 wheel disk master cyl. (for the proper piston bore)?? much obliged in advance /forums/images/graemlins/1zhelp.gif

You should be ok. Just watch your fluid level, as disc brakes take more fluid, and as your rear brakes wear, your fluid level will drop. The stock brake master cylinder doesn't have enough fluid capasity for disc brakes. Good luck!!
