Brakes were perfect before this. I drove down a really steep hill (about one to two mins from top to bottom) and then I was getting squeaking whenever I wasn't braking. It did it the whole way home, and while it was hard to tell which side it was on I felt the wheels when I got home and the front drivers wheel seemed quite warm. What would cause the brakes to stick after being heavily used for a short period of time? I have driven down (other less steep) hills with this vehicle before and never had the issue. Thanks for any ideas!
