PhotoHunt: What IS that???
That my friends is not what you want to see when changing the brakes on a car!! This is a rotor that should have been replaced a long time ago. A rotor should be smooth for those who didn't know.
And this is what you get when you think your children are playing quietly in their rooms. They place a magnetix piece on a light bulb that has been on for a few hours!!
It did not come off of the light bulb so had to replace it.
