Roy, I'm not sure what you mean buy is the proportioning valve calibrated for my brake system ??. I cannot ask the people I bought the brake system from because I bought the booster and master from Eklers and the Proportioning valve from Fatrodder on ebay, I probably should have bought a complete setup.
I rechecked all my brake lines (Checked good) and rechecked my rear brakes to make sure I assembled correctly All tooked good.
I checked to see if the warning sensor had be activated with my ohm meter and it was not activated. I tested it when I rebleed the brake system again.
Just a note: If you look at the Picture of the engine compartment you will see the vacum canister with a guage on it. When I stop the engine the vacum will hold at 17 for 20 minutes.
