you have a leak... check all your brake lines and calipers. Something is badly amiss.

You might have to add dye to find it... but don't drive it until you do.

:cheers:

Can you see fluid leaking at the wheels( will likely be in back, by the calipers)

Any fluid on the ground, under the car?

Any fluid missing from the Master cylinder reservoirs? ( I should have started here :rolleyes: )

If fluid is fine, and the pedal still goes to the floor, you may have gotten a bad MC.

Are you sure it was new and not a reman?

:seeya

No leakage - Brake does pump up - then progressively goes back to floor - it was a new Delco factory Master cylinder. Could it possibly be my Booster?Thanks to all who have answered.
