Is this a car with ABS, or without?  I'm guessing without, given that
it's a '00 Kia, but ABS system failures can do this, too.  But bypass
failure of the master cylinder is a quite likely cause.  It's what I'd
replace, as well as the fluid.  It's probably 10 years old, and
causing substantial corrosion.

A master cylinder for tis car will be cheap, and its not hard to swap.
 Teach the nephew to do it, which is likely to impress the
girlfriend...
