OOOP's What have i done now (BRAKES)

[bbobb]

I recently installed a 4/6 drop that included the drop spindles, springs and shocks. I also relocated the shocks with the brackets in the kit. While I had her torn apart I went on ahead and installed a brake boost seeing how I had disk brakes on the front. The booster is where it gets ugly. When I hit the brakes she pulls real hard to the left when I pump them they get real hard and then after a pump or two they get to pumping and settling like power brakes normally do. What have I done wrong and what do I do to correct this. Thanks upfront for any and all help
