Proportional Valve, Pressure and adjustment
Hello,
Re: 1985, F-250HD, 4x4, 460ci, XLT Lariat
Just purchased a CPP Master cylinder and the HydraTech Hydro Booster combo.
The CPP Master Cylinder has an internal proportional valve with adjustment for Rear Brake Pressure and Maximum allowed rear brake pressure.
I am running disc on the front and drum on the rear. I know the drum brakes can not take the same pressure as the Disc but what is the maximum break pressure I should allow to the rear drums? I don't want to be blowing out the cylinders. Note that I will be removing the rear load sensing proportional valve that is connected between the truck bed and rear axil via a pair of half moon arms. I understand these are prone to problems and don't work very well. So the rear brake line will run directly from the CPP Master Cylinder to the rear brakes
Does anyone have any advise on adjusting the proportional valve? The end application for the truck will be pulling a trailer
Thank you for any advise
