mine had no issues with the swap. It would lock up the stock rear drums with little effort. When i switched to the disks in the rear it was still a little touchy so i now run an adj. prop valve in the rear.

Is you MC still good?
Have you changed the stock prop valve?

I Was Told That I Didnt Need To Change The Prop Valve. I Have Used Many Diff Types Of Mc, Even A New Stock One

Try making a piece of brake line to bypass the prop. valve just to see if it gives you more stopping power. It may lock them up, but atleast you will know if you need to put in an adjustable prop. valve

I converted mine to disc. It seemed to brake fine until one day when I hit the brakes a little quick while flying down the highway. The rear locked up and it was pretty interesting for a few seconds. You might say the pucker factor hit an all-time high.... I'm going to put the valve in the rear line and run a guage to each caliper just so I don't neet to worry about it again.
