    The light on my dash that lights up when the emergency brake is on and the emergency brake is not activated. when I do activate the brake the light lights up even more. There is no evidence that the brakes are rubbing, that I can tell. What things could it be or what could I check?

    Disconect your battery for a few min. and see if the light goes out when you hook it up again /forums/images/graemlins/dunno.gif

    Almost sounds like the e-brake switch is screwed up.

    Never heard of a brake light that used varying voltage to indicate something. On/off, yes, but not varying voltage which is what you are seeing.

    You could probably unplug the switch and see what happens. Believe the light should come on with it disconnected. Just follow the e-brake pedal up to near where the cable connects, should be a single wire and a connector. Been probably 5+ years since I've looked at one, but I think the wire for mine is brown.

    Hows your brake pedal feel? Is it soft and mushy, or normal? I had the brake light come on when I had a bad brake cylinder in the rear, the brake light can be activated via the proportioning valve. You can try unplugging the wire from the prop valve and see if it goes off.

    i'd venture to say the little switch is sticking in just enough to make it arc some current - hence the light being on and when the e-brake is engaged, pushes the switch so it makes full contact (more current) The switch for the dome light in my door was doing that on a diff. vehicle i had, i pulled the switch out and worked a tad of WD40 so the switch freed up. Worked perfect after that.

    When I first noticed it the pedal seemed a little stiffer and it would stop abruptly when applying the brake at slow speeds (like slowing for a stop light). That is the only difference in the feeling. I don't notice the stopping like that anymore. It has been two weeks.

    I will try all of the suggestions and keep them coming.
    Thanks
