I've tried most of these things and my pedal still goes down. I can pump the pedal and it's higher but doesn't want to stop. New master cylinder, trick rotors and pads, stainless steel brake lines and Motul racing brake fluid after fluid flush. Computer aided config of ABS and I still hear a noise like a doggie chew toy inside the cabin when I push the pedal. I drive my car hard and it's scary with these brakes. Anyone have the chew toy sound in the cabin?
