Ok well, I had drove the car earlier in the week with no probs , then a few days later, go to take it out of park, brake pedal drops to the floor and she starts rolling down the driveway . Opened to MC and there was no fluid, looked underneath and at the tires and I don't see any fluid anywhere

I would think if it was a wheel cylinder there would have been some fluid on the inside of the tires, but all dry, haven't taken the tires off yet though...

So I replaced the MC since it wasn't very expensive and still nothing . When I go to bleed the brakes, the back brakes will bleed perfect, but once I get to the front, it seems as if the air never ends, I am thinking a brake line somewhere, but can't find any leaks so far.

If anybody has any other suggestions, I will be happy to listen

Oh yeah its for a 51 Chevy Deluxe, Drum/Drum, manual brakes
