Parking brake light cuts on magically.

Ok so basically every time I take a hard right turn, or accelerate heavily my parking brake light cuts on. The parking brake is completely released, but I can't figure out why it continues to do this.

Re: Parking brake light cuts on magically.

Check your brake fluid, could be just low enough for it not to be on all the time

I'm a simple man, I like pretty dark haired women and breakfast food.

Re: Parking brake light cuts on magically.

I have that same exact problem too. Whenever im offroading and bouncing around the light comes on cause the hand brake comes out a little bit. I think its because the parking brake is a little loose or the the springs are a little worn out. Its no biggie since all i have to do is push the brake back in.

you can check that pretty easily, there's a switch somewhere along the stick that activates the light, you can duck under the dash and see it it's being tripped, otherwise with a multimeter if you're not sure.

Is probably the level, though.

Re: Parking brake light cuts on magically.

How exactly does the sensor work? I helped a friend change his rotors and pads, and bleed the brakes, and his light is on with fluid topped off. The light has never come on like this before.

Vrrm pssht!

If you're asking me, I'm not really sure.

The sensor on the emergency brake lever is just a simple contact like the clutch start cancel switch.

On the brake fluid reservoir there is a connector, but how the sensor works and what it measured, I don't know, maybe someone else does.

I would probably try and take the reservoir off, shake it, see if I could figure out how the sensor worked and fix it.
