Rsc light came on
 

Driving home my RSC on my 2008 Mercury Mountaineer came on Then my ABS and traction control light came on. I tried to pull out and could go 10 feet and then wheels seemed to lock as if I were pushing my brakes. Changed braked and rotors still didn't go. Step dad removed ABS relay fuse(?) and we were able to drive it home. What could be the problem?
