My daughter complained about her brakes. Left front was worn down to the metal, inside was like new. Replaced them in March. I replaced the caliper, my son and I have bleed the brakes to remove all the air. I have a stiff brake pedal when the car is off, but when the car is running the pedal goes to the floor. I assume the master cyliner is also bad, it doesn't seem to push the caliper piston out. Any answers. Thanks........
 
will the brakes pump and hold psi, if not possible bad m/cyl. remove m/cyl and try to bleed on binch, make sure the plunger is not stuck at bottom of bore. when bench bleeding make sure to keep both brake line outlets coverd and let the psi off gently and cover then before releasing the plunger.
after bench bleeding reinstall m/cyl connect lines and try bleeding againg, rember to start at rt rear, left rear, rt front and left front, do not let the resivor get low of fluid keep about 1/2 full at all times.
 
Mom's 00 malibu did that to me. First off did you read up on bleed procedure? It was the first one I did that needed a front bled first and then a rear. Not sure if they x patterned or not. Found out after much hassle, the antilock if air locked, needs bled by way of scan tool?? Was long ago but that's what sticks in my short memory. HTH. Fred
