Brake valves missing
I took on a 47 Ford coupe 302cuin AOD trans. as a repair job for no rear brakes. I discover there is no metering or proprotioning valve in the system. And I verified the rear brakes are not activating. I'm thinking I could install a adjustable proportioning valve in the back, but I'm not sure about the metering valve for the front. Are there certian types you have to have?
