I have a 2001 Taurus that I am on my wits end with. The brake pedal sinks to the floor.

I have replaced the master cylinder twice...Advanced Auto, after market......Still goes to the floor. All the brake calipers, rotors and brake lines have been replaced!

No Codes on the ABS. I have a Launch X431 pro Mini Scanner. I have pulled the ABS and tried to clean in Ultra Sonic and blown out. Activated the valve via scanner seems to be alright No Codes for the electronics Module.

I must of did a full bleed 10 times now....Still goes to the Floor?????????? WTF could be wrong???????

If you have rear drums, check the shoes are close enough to the drum and that wheel cylinders have no leaks.
