Might be a vaccume leak in the brake booster.For first time there must be enough pressure for the workin of the brake booster but durin the 2nd and third application due to the leak it might not be able to generate enough pressure for smooth operation

I think guess that the brakes would had regained its bite after you down shifted?

Anyway,it is the brake booster problem and is due for a replacement. When the diaphragm(Booster) has worn out hence it does not create enough vaccum for repeated braking, however on facing such a situation suddenly,it is recommended to downshift to the lowest gear(say 4th to 2nd) possible,here you will find brakes pressure coming back.

But as i said please have your brake booster checked

I had the same problem with my truck and it was because of the booster. I had to get the booster and the master cylinder replaced... but it was done FOC as it was covered under warranty!

IMO...i have observed this in my car as well. you are basically pumping the brakes and hence more fluid is pumped. this makes the brake paddle hard and braking is more effective. this also allows you to control locking up the wheels just as ABS i guess.

Its a booster issue and quite common on Scorpio, the one I drove in Calcutta needed double pedalling constantly to give any sort of braking, don't take it lightly, it could lead to dangerous situations, one that could be fatal, have it rectified ASAP by the dealer.
