Emergency Brake Light - Goes on intermittantly

1698 Views 16 Replies 16 Participants Last post by  Keep
Hello Everyone,

This used to happen ever so often, but the last month with the weather being -40ºC at it's worst, this happens almost all the time.

The Emegency Brake light on the dashboard goes on, and stays on when it's really cold outside. If I accelerate hard (warms up the engine bay slightly) the light goes off for a moment, then back on.

When it's warmer outside, the light goes on rarely, but as the weather dips, the light goes on quite often.

So basically my e-brake light is now a outside air temp gauge! haha. I've already checked the switch on the e-brake handle, and that switch is working fine.

Has anyone seen this? Have any insight onto which system is failing?

Check ur Brake fluid level!

+1
+2

Had the same issue. Was a leaky brake line on the front passenger side. Replaced the line, filled it up, unstuck the floater in the resevoir, and viola!!...no more light.
+3 had the exact same problem. Added more fluid and i was good.
+5, low brake fluid was the problem. Got this fixed about a couple months ago.
check your brake pads too. that could be why your level went down

Unless of course you're like me, and just LOVE changing your rotors every 14 months. :disappoin

lol. that was me who said it a few weeks ago =)
+6 Lol. Just happened to me too - only on the coldest days and it would go off during acceleration and around turns. Front right caliper was leaking, replaced under warranty.
my brake light just stays on forever, i had just changed my brake pads, filled up my brake fluid, and changed my brake line, but brake light still on...wtf is wrong??
Look at wiring diagram, that light is triggered by 1 brake fluid level sender and 2, parking brake position sender (switch, sensor, etc.) so the float switch may be stuck, or your hand brake is not fully released.

I had this problem...and I needed new brakes. The farther down your pad gets worn, the lower your brake fluid level, as more fluid is needed to push the calipers together far enough to stop the car. Replaced my brakes and light is no longer on. Don't wait too long to do your brakes though, I had to replace a rotor that got EXTREMELY grooved.
Thank you everyone. I'm sorry that this topic had come up before.

It was low fluid, but lazy as I was at the moment, it didn't even occur to me to check the wiring diagram. Lesson Learned!
