Default No Clutch Pressure...

1987 Corvette with 4+3.

I haven't Driven the car in a few weeks because of snow here in Iowa, but I went to start the car today and I had no clutch pressure, it just goes right to the floor with little effort. The Master cylinder got changed over the summer and after that I had a nice stiff clutch pedal.

Anyone know what the problem might be?

I looked in the factory service manual but did'nt see anything like this in the diagnosis section.

sounds like when i forget to make sure that my throwout bearing was attached to the fork...but i had the transmission out...if you haven't pulled anything, then i dunno how that could happen...unless there is a line seriously leaking.

I actually didn't change the clutch master cylinder, the previous owner did. I bought the car in september, and have had zero problems with the clutch until now. Nothing looked wet around the master cylinder...

Is the clutch still working or weak pedal pressure and not working?
