prop. valve
I run a Dodge Caravan aluminum master cylinder and don't think that I need a pro. valve at all. I have a Summit adjustable one installed on the rear with it turned up all the way and don't see the point of it being there. Isn't the point to be able to adjust if one locks up before the other so you can get max braking. I was told I needed one on the rear because "with the light back end of a pickup it will lockup the rear brakes easily" maybe with the stock wheels and tires on it. I never had that trouble when I had normal size radials front and rear either. Maybe I'm just lucky and the Caravan M.C. just works well.
