Sorry if this has been asked before if im in the wrong place its my first day on here and new to forums, if i am can someone point me in the right place.

Bought a 2.0 Zetec Focus W reg for what i thought was a great price and apart from this problem its spot on. Lad i got it from was a friend ov a friend and he said needs a new abs sensor on front right or as there is a bearing in the glove box someone has put the bearing in wrong or wrong bearing altogether and has had to remove the ABS fuse coz that wheel locks up. So thought fair enough hes told me wats up for the price cant complain.
Havnt change the bearing but did put new sensor on and replaced the fuse and the wheel no longer locks up and codes pointed to that wheel but ABS light, Traction light are constantly on and once hit just over 10 mph handbrake light comes on. Could this be the bearing, i dnt pretend i know everything but if it just the magnetic pick up on the bearing surely the lights would not come on till i start moving and its picking movement up or could this be something else. I have done a voltage check to each wheel sensor and have checked that there are no brakes in any wires to the plug on the ABS unit and all are fine and very close readings to each other. Please give advise its really annoying me.
