My brake light is on every cold morning when i turn on the car, major problem, after driving for like 15mins goes away, any 1 else have this problem???

 

brake master cylinder cap.

 

what is that? how could that affect with something like that

 

The brake master cylinder cap has a fluid level float. It will turn on your brake light once your brake fluid level is low. Check your brake fluid level. If the fluid level is ok, disconnect one of the two wires that goes to the cap. If your problem goes away, you need a brake master cylinder cap. Your brake master is located on the driver's side firewall under the hood.

 

thats a common Toyota problem i heard.. your e-brake light still stays on right? its a sensor thing. you still got warranty?

 

yea i still got warranty, hey sg thanks for that info i'm gonna check on that.

 

they just replaced my brake reservoir cap for the same condition, since then, no more light

 

Yep! More quality product from Acura. Covered by warranty.

well its not like the cars are hand crafted or anything

 

Ya, I've got the same problem.
See thread previous thread "Brake Light", where I said "Anyone have this problem?
When it is cold out, the "BRAKE" warning light stays lit, though the brakes seem to work normally.
If it's not too cold, it will go out after the car warms up.
If it's really cold it will stay on.
I've had it to the dealer, but it wasn't cold out, so it wasn't lit.
They said it all checked out OK.
I don't want to keep trudging back to the dealer to have them tell me that they can't reproduce the problem in their nice warm garage.
Any ideas?"



Will check the cap thingy. Sounds like a good approach

 

I have the same issue - let me know how it works out
