EBrake light/Antilock lights illuminated...all the time.

<hr style="color: rgb(209, 209, 225); background-color: rgb(209, 209, 225);" size="1"> Have a soft pedal, almost to floor...she'll stop ok...
Need direction to a laundry list of "what to check" and eliminate from there...
Brake fluid level ok. No leaks noted.

AE won't help me on this one!

both lights on means a fluid problem. Bad sensor or no fluid. Sounds like you have more than one problem though. Have you tried bleeding them?

I have been down this road for 3-4 years with mine With the lights(black tape worked for me) , no soft pedal though . If your pedal is soft & not normal , you may have a leak.. If the res is not low , it is most likely a bad master cyl...

I vote for air in the system. Gravity bleed them, that's what worked for me. If not, then the MC is shot.

Those do need to be checked. Most people have sticking parking brake levers in the back. Or sticking cables. If they don't release all the way on their own then you will get a low pedal. It won't set off the lights though.

Light indicates vacuum indicates low vacuum as well.

Both lights are fluid. It's like that on all ABS equipped Fords since 1988. On one without that stupid sensor on the front it is actuated by the fluid level sensor. I'm not sure with a vacuum pump system though. On mine just the red light comes on with no vacuum. If I unplug the level sensor both come on.

My truck had the soft pedal and both lights on too. We figured out is was the RABS Valve...

Replaced it and ajusted the rear, and all is good now. Just a thought... I got my valve from NAPA, same warranty as the dealer, just $200 cheaper...
