The brake pedal goes all he way to the floor and I can hear a hissing sound as I depress the brake pedal. Pressure doesn't build up as I pump the brakes. So the thought is the Master Cylinder not the brake booster? What about the Master cylinder moving back & forth as the brake pedal is pumped?

That doesn't count..at all? Lol. Or are you looking for something more? Either way I'm just saying what I said cause outta nowhere my pedal hit the floor in the Durango and I checked all the little stuff and didn't see leakage anywhere and thats when I took it to the shop and they found the wheel cylinders leaking which is what I expected cause it was the same symptoms as my Dakota. I'm only throwing it out there as something else to check.

As I said before the pedal goes to the floor but I haven't had a chance to see if thc booster is moving when the Master cylinder moves. I will pull off the rear wheels/brake drum to check the wheel the wheel cylinders but since the Master cylinder stays full, I don't think they are leaking. Any recommendation for a Master cylinder? I checked at the local parts store/ebay and prices can range from $20+ to $70+.
