Brake pedal goes to floor when engine is turned on, waiting for Red light to turn green pedal will go to floor if pushed sufficiently, pedal is generally soft, spongy. Brakes stops car. ABS works fine, no indicating light on dash. New Rotors, Pads, Brake fluid, Master cylinder, Booster check valve replaced.
No leaks. ABS Modulator shows no leaks.
Maybe the ABS Modulator electronic control bad?????
I am at wits end, haven’t taken it to the Dealer.
Any suggestions?
