Parking brake light coming on/staying on intermittently...

Started a few weeks ago when I'd accelerate from a dead stop. It'd stay on for a few seconds and then go off. But as time has progressed, it's been staying on for longer. Now it'll stay on all the way up to top city speeds.

Any idea what might be throwing the sensor?

Have you checked your master cylinder reservoir? On my 2000, low level will turn on the light.

If the level is low, it could simply be wear at the discs, as the piston moves slowly out when the pads wear. On the other hand, it could be a fluid leak at a wheel, line, ABS module, flexible lines, anywhere where there's a fitting. Obviously, you'd want to check that.

If it has been a few months just wait until something breaks. That is the way to narrow it down? I usually try to get at the problems when they actually begin. Seems to favor success and sometimes it is not the easy fix. If you are not sure just go to a good brake shop. The brakes could save your life. An important feature to be on top of. Sometimes a dragging rear shoe will start a bearing fire. I have seen the results. Do you have an extinguisher in your car? I never leave lights warning me for long. Just be safe and get some qualified help. It is more than you have experience with.

Step 1 Check fluid level & top up if needed , Step 2 Get a strong flashlight and look at the brake lines and behind each wheel for leaks!

My brake light has been on ever since I bought the car over a year ago. It doesnt affect the function(aside from maybe the ABS not working but I havent locked the brakes up to find out........ and hope not to have to use that). Aside from the fluid being low, it could be a parking brake sensor going bad(the one connected to the ebrake), or it could be the float in the master cyl gone bad as well.

This is a decidedly Darwinian diagnostic method when talking about the brake system.

Yes after reading post here I am beginning to see a pattern of neglect and confusion related to care of the fine Taurus machine. I had the very same brake light come on and when I took a look around the old brakes I found that the rear brakes were almost to the metal. I had just bought car so instead of waiting I got brave and took a look. After the new rear brakes were back on the light mysteriously disappeared. Just like magic!!

No need to turn into a douche. And I never said anything about the light being on for months; I said it's been happen for a few weeks and only recently did it begin staying on for more than a flash.

Not a douche, just have noticed other people in similar situations. Only saying make sure it is not linings or pads. That is just being safe!! The warning lights can be a pain or set off with out a problem. Usually there is more than just the light. Hope you find the easy fix~~
