Well, as I am guessing, something inside one of my rear brake hubs that
is supposed to be a part of the hand brake, fell off and is rattling
around the hub. I know it has something to do with the hand brake
because I noticed that my left side hand brake is not working the same
time I noticed the sound by the left rear wheel. I tried rasing the car
in neutral with the hand brake on and I could turn the left rear wheel
without much force.
