Go home. Take all the brake components off and put S cam air brakes on it. Problem solved.
Can't remember if you said you checked the rear brakes or if this has been suggested. Have you pulled the drums to make sure you don't have a bad slave cylinder?

That which does not kill me had better run pretty damn fast.
Sticks and stones may break my bones but hollow points expand on impact.
SO-- Got it back from the mechanic today...guess the lines just needed to be bled even further...He said that the seal on the axle is bad and gear lube is coming in from the dif, making my rear left drum brake pretty much not function at all...He priced it out at 2 or 3 hundred dollars, can't remember. Anyway, it can't stop on a dime but its a whole helluva lot better than it was before I brought it to him. Figured I'd let you guys know
