Abs relay valve has been discontinued. I have read that people have put a standard brake relay valve and disconnected the abs. Does anyone have a part number for compatible brake relay valve?
The brake valve under front of bus is leaking out of both ports

I replaced my rear ABS valve last November with air brake relay valve part number S4898 by newstar from Find It Parts. I beleive the front and rear ABS valves are the same.
