2008 Ford Escape 2wd 4cy. Brake pedal slowly goes to floor when applying the brakes and sometimes im not sure if im going to stop. I purchased the car this way and have been trying to chase the issue. So far I have replaced the following: New pads, New shoes, 4 new brake hoses, new brake power booster, brake master cylinder ( really thought this was the issue so after it didnt fix the problem I thought maybe i got a defective one and replaced it again). I have blead all the brakes starting at pass rear, then driver rear, then pass front, then finally driver front. Yesterday I gravity blead all brakes again. So far I have ran a gallon of brake fluid through the lines. I do not see any leaks on the calipers or wheel cylinders. Still, when I start the car and apply the brakes it just slowly goes to the floor. I am at a total loss with this. Could it be something to do with the abs system? There is no abs light on, and when I press the brake pedal I can hear a relay or solenoid click. If anyone has experienced this and has more knowledge please let me know. Thank you.

 

You will need a scan tool capable of activating the ABS module when you bleed the brakes.

 

Sounds like the classic bad master cyl leaking internally. Wouldn't be the first time to get 2 bad master cyls.
Where did you purchase them also were they bench bled before installation?
