Parking Brake Indicator Light stays on. My 1988...

Make sure that the E-brake is totally up (or) disengaged

Try the parking brake release. On a car that old you MAY have a sticky parking brake cable that's partly engaged. If this is the case, it would freeze up in place and cause the sending unit for your brake light to turn on/off at random. -they use the same light for brakes and parking brakes- If your brake petal has become less firm or "spongy feeling" recently... then it's an issue with the brakes themselves.Also check your brake fluid level.

First of all, the abs problem... NO do not start there, start with checking your brake fluid.. thats the number one cause for that light and no other lights on your dash to be on... if that is your problem fill it up and address the brake leak... brake fluid doesnt evaporate and your car doesnt use it up. if its low its going some where best way to do this is park on a clean surface or slide cardboard under your car pump your brakes 10 times and then examine the cardboard or move the car and look for wet spots that wernt there before or you could also have a friend lay on the ground a few feet back and look for drips while your pressing the brake pedal careful not to get any brake fluid in the eye it burns like no other... if you find a leak have it fixed if you dont it might still be a internal leak into the power brake booster and you should have someone look at it NORMALLY when you have a ABS problem with you car BOTH THE ABS LIGHT AND BRAKE LIGHT will be on not just one but the other awnsers could be correct too the brake indicator light does come on when the emergancy or parking brake is enabled try pulling the release and pull up on the parking brake pedal at the same time.. or if its a center parking brake push it all the way down with the button pushed

Pull up on the brake pedal, see if stop lamp goes out? You may need to check stop lamp switch and brake pedal arm? Pull that fuse in diagram, see if it kills the stop lamps? At the bottom left, in diagram, see the green wire with yellow tracer, that wire should not be hot unless you step on the brake. You can use a test light to check for voltage. good luck

There is a fault in your brake system. It could be something as simple as the reservoir being a little low or this could be an indicator of a larger problem. Check the fluid level, brake pads and shoes, and that the calipers are operating correctly. If all of this checks out then you will need to look at the brake Distribution control, ABS module and Master Cylinder.

If your rear brake shoes are worn down enough there is a chance that the tension spindle in the wheel is failed open/or broken.

Your brake light is out.
Check brake lights and repl. burnt light bulb .

The indicator light is there to tell you your brakes are out of adjustment just remember that if you just replaced your brakes that your parking brake may need adjusted this will make the light stay on also.

is master cylinder full, also check that parking brake is released and it switch is operating

I HAVE SEEN A BAD BRAKE LIGHT SWITCH.CAUSE THE ABS LIGHT AND BRAKE LIGHT COME ON.WHEN SWITCH WAS REPLACE BOTH LIGHTS WENT OFF.
