Dashboard Brake Light Will Not Turn Off ('82 Celica GT, SRA)
« on: Nov 29, 2020, 07:54:41 pm »
The brake light in the dash that signals when the handbrake lever is pulled won't turn off.

I read on a couple other sites that the light could mean low brake fluid, or a problem with the master cylinder. I bled the brakes all the way around, and made sure there was enough fluid in the reservoir, and the light stayed on.

I also checked the wires leading to the sensor under the lever. One side gets power and the other is a ground, like it should be. I'm not sure if the switch under the lever is broken, or if it could actually be the master cylinder or something else.

Has anyone had this happen before? I need to get my car inspected soon, and I'm not sure if this will fail it. I had the same problem with my Subaru a couple years back, but that was fixed by just adjusting the tension in the cable, if I remember correctly (I think the tension in the Celica's cable is fine).

How's your charging system working? Brake light staying on can be caused by the voltage regulator in the alternator failing.

Maybe low brake fluid? That will also trigger the light, check the easy stuff first.

Funny enough the alternator was bad and I replaced it, but the light is still on. The car wouldn't start despite the fact that I replaced the battery only a few days beforehand. The light next to the voltage meter is still on (which I assume is an alternator light), but all seems well.

Is the alternator charging? Like 14V+ measured at the battery?

If it's charging the charge lamp relay likely decided to not work any more. It's located in the fuse panel in the left (driver's) kickpanel. The problem is Toyota doesn't make them any more...

check the connecter under the center consul if its good check the plug by the parking brake shoes, something is still getting a signal, that happened to mine as well but it was so long ago, i remember it being a problem through the hand brake system, more in the back of the system  by the shoes
