Okay GL, forgive my stupidity, but what is "bedding" the brakes?
I just made that up to sound smart :ummm:
Ok ... I'm joking. But don't feel stupid, I didn't know what this was until a couple of years ago. But it all makes sense once somebody explains it to you.
For optimal performance, you need to maximize the mating surface of the pads to YOUR specific rotors. Both are generally flat, but not perfectly flat. So you want to really get those nitty gritty contours to be fully mated. On mine, it was pretty bad, because as I noted, only about half the rotor was being used (e.g., abraded) but after, I can see that the whole width is being used.
You want to have a nice even and smooth transfer of braking material going to the rotors, rather than friction causing the brakes to wear in one area, but not another.
Also, there is something magic about getting them really warm gradually, then hot, and then allowing them to cool down. But I am not a magician, and don't understand this, so I just do what I'm told.
Anyway, here is some more extensive reading on why and how to bed the brakes. It really does make a significant difference. Also, a good bleed afterwards doesn't hurt, just to make sure there are no more air bubbles. Especially if you had a dry component, or components, as I did.
