All, before I changed my rear brakes and rotors on my 9-7, the pedal would sometimes go too far down and other times be fine. I thought it was due to the piston traveling too far as the rears were down to metal. I put on new rear pads and rotors and verified the fronts were new as the dealer indicated. The pedal situation never changed. Basically it is a crap shoot as to if the pedal will be nice and hard and the brakes will grip as intended or the pedal will go too far down causing you to need to pump them to get full breaking power and the cycle starts all over.
Given the pedal situation wasn't related to the pads being worn though the timing seemed to indicate they were related what do you think?
Possibly a master cylinder? I didn't bleed the brakes when I did the rears but I'm a bit confused as to what this could be. Sometimes the brakes will be perfect and others require pumping on the same 25 mile drive? When they work they stop great and when they don't the stopping power is cut down.
