need a lil' help guys. my "BRAKE" light stays on when the cars in high boost. didn't happen before but started few days ago. brake light come on and remained on for a while then it goes out again then comes back on when I floored. Could it be just a fuse or what??? any help will be great thanks!

 

Have you checked your Brake Fluid level?

 

fill the brake fluid tank, you must miss oil.

 

My car did the same thing. If it is not the brake fluid, it could be the emergency brake. It gets loose and under hard acceleration it comes up enough to turn the light on. I had mine adjusted about a year and a half ago and it solved the problem. It feels like it is getting a little loose again already.

 

Mine do the same. It's not the fluid. It the E-brake loose. Same as problem with CPA.

 

Is there any chance that the one-way valve that feeds vacuum to the brake booster is malfunctioning, allowing pressure into the booster, causing some sort of alert?

 

yeah it's E brake light that comes on. I checked the brake F and it's up at full level. How do I go about adjusting it?? do I adjust inside where e-brake is or under the car??? could I do it my self of take it to the shop???Does it do any harm to the car performance wise or maintance wise??? Thanks for the support guys!!

 

I might second Bajaman's suggestion. Try the e-brake thing, and if that doesn't help then check the 1 way valve.

Don.

 

it will be the ebrake thing watch it as you accelerate.it will move a little mine does it

 

I also thought mine was a loose E-brake, I checked my brake fluid, it was only a little low. I topped it off and NO more brake light.

 

Not a real suggestion, but I had this problem and it ended up being my brake pads.

I agree with the others, check the e-brake first. There was a good post about this about a week or two ago:

 

thanks for that "How To" instruction Mahjik. I will work on it tomorrow and post up the result
