I concur with the other poster's diagnosis. An easy test is to remove
your foot from the pedal while stopping and then reapply the brakes.
This is called pumping. At least this used to be the best way of
checking for a bad master cylinder. Modern ABS systems are tricky, but
I can't think of any reason why this would not work, even with ABS.

The pulling hard to the left is most likely the result of the same
problem. The equalizer valve that distributes fluid pressure equally
to the front wheels may be confused by the sudden drop in fluid
pressure as the pedal bottoms out. However, checking and replacing the
front brake pads is very easy so you should do that anyway.
