Q: Why is my brake warning light on sometimes?

asked by on September 21, 2016

My brake warning light comes on every now and then while driving and also after it sits in park for about a minute or two. I'd say that 75% of the time driving, the light is off though. The brake fluid is full, didn't have to add any either. Seems like it goes off most of the time when I have to take a sharp corner or sitting at a stop light/sign or hit a bump (doesn't matter what size bump).
My car has an automatic transmission.
