Brake Light Still On
Recently I was driving my '85 F-150 4X4 when the leaky LR wheel cylinder failed and the brake pedal went to the floor. At the same time I noticed the brake light illuminated in the dash. Well, I have since replaced the wheel cylinder and purged the air out of the brake lines, but I'm wondering if there is something I have to do to make the brake light shut off.
Thanks,
Justin

Get to one of the front calipers and bleed it like you did the rear. You mayhave to push hard on the pedal.
There is a small piston in the proportioning valve that seperates the front brake system from the rear. If one of the systems loses pressure, the pressure from the good side pushes this piston off center, and grounds a wire going to the proportioning valve. This turns the light on in the dash. What you need to do now is somehow get the piston re-centered in the proportioning valve, so the light will go out.
