ding noise while hard braking
 

Ok so this morning I had to do a panic stop hard brake from 60 ish to zero. And avoid a car in front of me. While this happened the dash made a dinging noise.. rapid ding I've never heard before. I didn't see any lights but I was sawing at the wheel to avoid the cars in front of me that stopped on 114.. I'm sure the noise was nothing and I'm not worried about it. But I'm curious if anyone else experienced this?
