Q: Why are my brakes squealing?

asked by on November 20, 2016

Break light has been on for a couple weeks and I didn't think anything of that it. Today my car started to squeal when driving and would stop when my car came to a complete stop. I heard a rattle too along with the squeal at one point. Ended up I needed to add break fluid so I did and it seems ok now but could that rattle of been something coming apart? Anything I should be concerned about now?

My car has 107000 miles.
My car has an automatic transmission.
