I just replaced the master cylinder on my truck. Bench bled, Bled the clutch side no problem. I have rebuilt all the brakes around the truck, sleeved cylinders, new hardware,relined shoes, new line, etc.. I have bled the brake system with a power bleeder at all points and I still can't seem to get as good of brakes as when I brought this thing home! I don't know what the problem is. The only thing that I seem to notice or that has been bothering me about the system is that the end of the cylinder on my hydrovac doesn't have a bleeder like it's illustrated in the book. The hydrovac seems to be from a 59' whereas mine is a 60'. Any help or opinions would be greatly greatly appriciated!!! Thanks!!
