    Dash brake light stays on

    In the 2nd gen I recently picked up, the dash brake light is staying on.
    I check the brake fluid, its full & brakes work fine.
    I also disconnected the wire from the proportioning valve & the light goes off.

    Any ideas or suggestions.

    TIA

    If disconnecting the wire from the proportioning valve turns the light off, and the brakes work fine otherwise, then the switch in the prop valve is bad.

    It's not a proportioning valve, just a switch to warn you if either of the brake hydraulic circuits fails.
    Very likely it just needs to be re-centered.

    A good slam on the brakes should do that, but in my experience (crusty old vans) it's often frozen in place.
