Swapped a 14 bolt sf in the rear. I had spongy brakes before the swap but figured I'd deal with that after the swap was complete. I decided to put discs in the rear from lugnut4x4.com. bled the crap out of everything and still spongy. Call a brake shop who advises a master cylinder made for 4 wheel discs. So I bench bleed and replace the master with the correct gm part for 4 wheel discs. After bleeding for days this guy gives up and takes my money and gives me the "That's how these trucks brakes just are," speech. Well, my pedal goes right to the floor and I slowly roll to a stop. So on to the next guy who bleeds the abs and suggests maybe the module is bad, so we replace the module/pump. Still can't get a good pedal. So at this point I'm 4 calipers, 2 masters, new rubber lines, 18 bottles of fluid, new pump/module, and abs bled, with discs in the rear. I bought the tech 2 to try and move forward on my own because all these mechanics are running me dry on funds. But now, I literally don't know what my next move is. I'm trying to tow a boat and I can barely stop the truck by itself. Any suggestions?? I'm thinking pinch off all the rubber lines but one at a time and see if i can find a problem wheel? Maybe pressure bleed also?
