    Same vehicle, another problem. My dad replaced the proportioning valve on his '83 RV on a one-ton van chassis. He bled all the brakes out but the brake light is still coming on (the idiot light). He knows it is coming from the valve, since when he disconnects the lead from it, the light goes out. Any ideas or anything special that needs to be done other than bleeding?

    P.S. It does have the hydro-boost system if it matters and in spite of the light, it just passed inspection too.
