OK! Installed the caddy calipers in the rear and think I may need a por. valve but don'y know for sure just yet. Now what I really need to know is If I install a 1 ton brake master cyl. on the truck would it give me a longer pedel throw and push more fluid to the rear calipers or anything like that. If so what year master cyl. and can I use the same booster I have now. (just extra info. I just pulled off the dana 44 calipers to install the caddy ones) Also looking for any pics. they may have how the e-brake cable is hooked up to the caliper or brackets to hold the cable.
