I agree with all of the above, I just finished this weekend the brakes on my 47 2 ton without hydro-vac and the peddle is hard and stayed up all weekend without any leakage, I rebuilt the wheel cyls. and a new master, adjusted all the shoes until they rubbed and then backed off. works great and my E-brake doesn't pull all the way back anymore. I like it!.
