"We're going to talk about the wear and tear on your brake rotor disc. This is obviously your brake rotor and once you get down to this point in the brake job usually we remove, removing the set screw but it's kind of rusted in right now, so you have to use other special tools when you get to that far along into it. But what you want to look for when you're looking at your rotor, just inspecting it like if it has gouges in there from the pad being on there wearing out too long. If there is a lip cut around due to the fact of changing the pads over a time period without replacing the rotor and getting it machined. So you kind of want to look at that. Let's turn it, and then it has a tolerance to it. So if you look at this surface right here you can see its thickness. Once it gets beyond a certain point then you have to replace it or machine it and that is basically what you have dealing with the removal of the rotor itself and your wear and tear on it."
