2000 Discovery II. My TC, Hill Decent, and ABS lights are on. I have recently replaced my front brakes but the light were on before I did that. I was hoping that if I replaced them that they would go off because the brakes were squealing anyway. I heard that if you clean your abs sensors on the wheels then they could make them go away. how do you clean them? Also, my rear passenger side wheel looks like it is literally spitting liquid like brake dust on the wheel. when I touched behind the wheel, there was a good amount of grease caked up. could this be why?

 

Once the 3 amigos comes on, you must use a 3 amigo type scanner to clear the codes.

 

Possible leaking o-ring on rear wheel hub, or clogged vent tube?
