Craziest Brake Job I have ever done

Can't tell you how many times I seen that when I was working. People would
come in saying it just started making noise.
The best one I had was missing the inside half of the rotor. Was driving it
into the shop and the pedal went to the floor. It fianlly poped the piston
out of the caliper.
It really scares me. People are really driving this stuff.
