I don't know if your E450 is like my F450, but I had the same issue after I replaced a rotted steel brake line in the rear of the truck. In order to get a proper and thorough brake bleed on my truck, the ABS pump has to be cycled during the process... one valve at a time. This requires a scan tool capable of sending commands to the pump. Since I don't have the cash for such a tool, I have to go to the local dealership for a brake bleed.
OUCH! i hope not! i never let the fluid level go too low in the reservoir, so i hope i don't have to go thru that....but we'll see!
