Do you have a separate parking brake light and a "regular" brake light? Most vehicles only have one light, it illuminates when the parking brake is set, but it also illuminates when the system detects a failure anywhere in the brake system.
You could have a separate light for the anti-lock brake system (ABS ).
Your description of a light that is on till you apply the brakes is usually a sign of some sort of system brake failure. Start with brake fluid level, then inspect the brakes at each wheel, looking for a leak.
If nothing detected there, then you likely have something more serious. (Master brake cyclinder bad, possible something in the ABS brakes, etc.)
Others may disagree, but I would suggest not driving the vehicle (except to a mechanic) until this is corrected.
if your abs light is on then there is a prooblem with the system, on your lincoln it is most likely a wheel sensor and not the abs box, go to your local auto zone and they will pull the code for free and tell u what is wrong with the system
Hi there,
If the light is on it means the ABS computer has detected a fault and it is disabled at present. You can try removing the negative battery terminal for 10 minutes then put it back on. Let the car idle for another 10 minutes and go for a drive . Try a couple of hard braking till the wheels lock. See what happens with the light. If it stays on then you'll have to get the computer scanned at the dealer's.
Let me know how you get on.
Cheers.
You most likely need to replace your brake switch, which is a
a $8 part. If you look up along the brake peddle you will see it depressing a switch. on the end of that switch is a electrical connector that you can press on one side to remove.
Once removed your brake lights will be disconected and your ABS
light should go off. You then need to replace the switch that it pluged in to.
I had this exact same problem, on a older bronco II. You need to get the ABS computer reset. You can either take it in or buy a computer your self. There are even packages that will allow you to use your own computer and just hook the car up to your lap top or desk top if you can get a cable long enough.
I never had mine done, because back then the computers were so expensive. I never caused a problem because it was only in the braking system. Now they are pretty cheap and there are a lot of other cool things you can do with them. You can reduce your gas requirements and set it for pulling, racing, and fuel efficency on the fly now. Just at the touch of a button.
