My brake sensor lights stay on when my car is off and locked how do I fix it or where is the switch located so I can unplug it to buy a new one can someone help me with that please and also is 24F 585CCA 730amp a good battery size for the car or it has to be bigger then that.

 

What is a brake sensor light? The parking brake light? ABS light? Not sure what you are referring to.
Perhaps a photo would help.

 

I think he's talking about the brake pedal sensor. It's right under the brake pedal.

 

It's not under, it's in front/above.
