I have managed to fix my front brake problems but it costs! My problem was the left side- uneven wear and pulling to the left. The dealer replaced the front calipers and put PF pads in the front. They sucked my brake pedal felt mushy and slow to respond. The second time less than three months later the dealer refused to warranty it citing a TSB listed at Fritz's site. They say my air bags are the problem. Put in camper, air up truck to stock heigth, rear proportioning valve does not provide more rear braking. BULLS###. Took truck to Les Schwabs, They have installed an average of 1 set of bags a month for five years on new trucks no problems. I did not have bags the first time my brakes went to crap. Sorry about the length but now for the fix. Schwabs installed a whole new brake set up. I will post the pads when I ask them on monday! Everything else was stock. They adjusted my rear brakes, they looked new! My brakes were better than new!! I added a B-D exahust brake and use it ALL the time. I also lengthend the shaft for the rear valve two inches, and felt an instant improvement. As for the one ton wheel cylinders, According to the info at fritz's site rear wheel cylinders on 2500 5spds and 3500 are the same size. Cause of brake problems diagnosted as rear brakes failing to self adjust, inadaquate front brake design, air bags did not help, hard driving. Look for spots on your rotors between the webs that conect the halves. So far everything is still great!
