You may need new pads and the CBS just doesn't know it.

Brake indicators can be caused by other issues though. You may have low brake fluid, or you may need to change your brake fluid (check the CBS), or you may just have a brake fault.

I hope this helps a bit.

Ya, that does make sense. I thought the CBS was reading off the wear sensor, obviously not. It's the rears. They are very thin. Even though the light went off I'm getting new ones tomorrow.
