I also had this problem a while back. You will also notice if you turn the wheel while pressing the brake it will go all the way to the floor rather easy. The shop thought it was the PS pump and rebuilt it. WRONG! The ended up having to replace the hydro-booster (kinda like how a master cylinder/vacum pump for a gasser goes bad). I'm not sure how much the part was, but I know it wasn't cheap. Good thing I have an extended warranty!! LOL /ubbthreads/images/graemlins/phoney.gif
