Brake Pedal drops after hard turns

If I take a big turn (let's say turning 90 degrees for example) at a fairly fast speed, while in the turn my brake pedal just drops to the floor. If I go to hit the brakes while in the turn, the pedal seems to activate ABS, it feels like. If I let up and hit the brakes again, they're fine.

So basically, after a big turn my brake pedal is gone, until I pump them, then the brakes are normal again. This only happens with big turns.

I've flushed the fluid already, so it doesn't seem to be anything relating to that.

Is this normal? Why's this happen?

Definitely not normal! My car gets worked in the corners at Willow Springs Raceway and never have an issue with brake pedal dropping. You need to check the entire brake system.

Bad hubs and/or sticking caliper slides and/or pads not sliding correctly. It's called knock-back, the hub deflects and pushes the pads back from the rotor and gives a long pedal. Happens to heavily beat on/R compound tired cars constantly. But check the hardware too, if that's sticky a little knock-back can get a lot worse.
