After having been unused for two years while restoring the car, time has come to take it out into life again. However, upon test driving the brake failure light went off. I cannot find anything faulty with the brakes, but can a jammed main brake cylinder (master and/or slave cylinder) make the switch flip? And if the balance in the two circuits is restored, does the switch reset itself or do one have to do that manually? I remember having read about this way back, but can't remember how it was. I hope someone can shed a light on this!
