Brake System Warning Indicator Light

55

Asked by Oct 16, 2015 at 01:05 PM about the 2002 Mercury Sable LS

Question type: Maintenance & Repair

The last couple of mornings while driving to work, the Brake System Warning indicator lights pops on for a few seconds, either just before I get to a red light or just after leaving a red light. Is this because there may be an issue or is it one of those things possibly affected by the morning chill? It has been around 55 or 60 each of the last few mornings but this isn't happening in the afternoon when leaving work when the temp is up near 90+/-.

Sounds like either the level sensor is starting to go bad or the brake fluid level is low.

Agree with Tennisshoes,but i will add,have you had your brake pads changed in a while?

Also check the switch mounted under the dash at the brake pedal, it tells the car that the parking brake is on & they often go bad or come loose and make and break contact while driving. When it makes contact the brake warning light will come on.

The brake light issue is resolved with the addition of some DOT 3 brake fluid. I looked at the switches and connections and they all seem to be fine.

The addition of brake fluid may have eliminated the problem for right now, but you DO STILL have a problem that needs fixing. Even if your brake pads and shoes have worn down, the amount of fluid that is in the reservoir should have remained high enough to not have tripped the light.
