1999 Plymouth Breeze brake light on dash does not go out

Hi bradm2. Welcome to the forum. First, verify the cause of the light being on. Unplug the low fluid switch on the master cylinder reservoir. If the light goes out, fill the fluid or the switch is stuck. Next, unplug the pressure differential valve below the master cylinder. Chrysler's pressure differential valve is spring-loaded but sometimes they get stuck. A good jab on the pedal often releases it. You might also, in rare instances, need to crack open one line on the master cylinder, then have a helper slowly push the pedal until the light goes out, then quickly tighten the line before the pedal is released. A stretched or rusted / sticking parking brake cable can prevent the brake from completely releasing and will also turn the light on. A clue here is the light will get just a little brighter when you apply the parking brake. It will be barely noticeable, but if you see a tiny change in brightness when you apply the parking brake, it isn't the cause of the light being on.

Happy I could help. As a side note, don't top off the fluid periodically. After a brake job or repair is completed and the fluid is filled, it will only go down if there is a leak or if the pads have worn down. We used to have to rebuild calipers at just about every brake job, but today they give so little trouble, we just push the pistons back in to make room for the new pads. Doing so forces all that fluid behind the pistons back up into the reservoir. You won't HURT anything by previously filling the reservoir, but that overflowing fluid will make a miserable mess on the painted surfaces and on the floor.

Come back and see me when you have another problem.
