1986 k20 Rear Brake Problems. PLEASE HELP!!

[Brad18xx]

i lifted my truck 9 inches (fully suspension) and i have this mechanism on my truck that connects to the frame and down to the housing that the brakes run through and i guess its for more stopping power when there is added weight. Anyways i had to unbolt it to raise the truck and now since it hangs there and its not long enough my truck stops instantly with vary little brake at all. is there anyway to get ride of the mechanism? also i know if i extend it that should work my i have no idea what position it was in to make it work right with no weight. i also need to do it without the bed because i have no bed right now. the bed adds weight. Please Help!!
