Quote: think you will need the proper residual valve for the drum brakes along with the prop valve---the residual is set at about 12" column pressure---this keeps your shoes in close proximity to the drums so that you dont have to pump up your brakes everytime you stop
Not saying I do or don't need it, but I've never had this in the past ever since I've owned the car. It always stopped just fine (well, fine for a 40 year old car). Is their any pics, or a place I can see what this looks like? Thanks.
