I have a 95 blazer that has the abs light coming on whenever I get to approx 15 mph. I have searched past posts and have removed the rotors. I cannot find any bolts that hold the sensors in the hub. I can clean the ring with sandpaper as they are easy to get at, but what do you use on the sensors. can I just spray them with something? thanx. wnk.

 

You might have to remove the brake calipers to get to them in the front. They have a single 10mm bolt holding them to the back side of the front hubs, remove them and clean the mounting surface to remove rust. Then re-install them...

 

I have removed the brake caliper and still do not see where they are mounted, do they have a shield of some kind over them covering this bolt? wnk.
