    50/50 chance, some people have had to, some people haven't needed too...just put all your stuff on and drive it around, you'll be able to tell if your stock prop valve will need to be changed.

    You can run it without the adj. prop. valve. I have been driving my truck without it since last summer. The only problem is that the rear wheels lock up real easy if you push too hard on the brake pedal.

    That is all I did. But others have not had the luck that I did. Here is a lengthy thread that discussed the disk swap problems. I hope it helps. /forums/images/graemlins/thumb.gif

    The only problem I ran into was installing my buddies disc brakes. We have almost identical blazers but his brakes WOULD NOT BLEED correctly. After an hour of furious brake pedal pumping, we compared mine to his. It turned out my bleeder screws faced up, his faced down. My caliper resovoirs were able to fill with brake fluid, on his the fluid went straight from the brake hose right out of the bleeder screw, thus never filling the caliper. We flipped sides and it tooks 2 minutes to bleed his brakes. So remember to reference the calipers so the bleeder screw faces upwards. Good Luck
