First ABS light comes on and goes off and comes back on. After a week of driving it like this, the brakes go all the way to the floor, but after pumping they start to work again. Brake fluid full!

Hello,

It sounds like you may have two problems, first is the brake master cylinder is bypassing causing the pedal to drop to the floor, here are some guides that will help you with that.

and

After you have replaced the master if the light has not gone out I would check the wheel speed sensors here is a guide to show you how that is done.
