Ford Windstar

I have a 2002 Windstar that keeps poping up with the ABS and Brake lights what can this be? Could it be the proportioning valve? We have replaced all the brakes also replaced the calipers and it still pops up with the ABS and brake light.

What do I do?

Abs system is different than the brake system
For the abs system you need to scan the van for codes
Possible sensor out on one of the wheels
Or if you check the ring gear for crack
Get the codes that should pin point the trouble area

Also check the float in the master cylinder ( it may be stuck at the bottom)
Make sure master cylinder full with fluid
Give it a good tap or two

Good luck
