1999 Ford Expedition ABS light?

I own a 1999 Ford Expedition with a 4.6L, it is 2wd, and has 4 wheel disc brakes. The other day when i was backing out of the drive way the ABS light in the i nstrument cluster came on. So the next day i jacked it up and checked the brakes on the front, they were worn so i changed them and hoped the light would go back off and it didnt. What would cause this warning light to come on and what do i need to fix or change to make it go off or do i just need to reset it some how? thanks in advance for your help1999 Ford Expedition ABS light?Yes, U do have to reset it, any shop with an ABS scanner can do it for U,
