There are two switches that turn the brake warning on. One is the parking brake switch, the other is a fluid level switch on the master cylinder.Metallman56 said:mine has the same issue. somedays its on, somedays its off. any one know the reason for this? i also get a oil light on every now and then. the thing is full of oil. i'm not too worried about either, car runs and brakes fine, its just annoying.
