Brake temp after cool down lap at rotor and caliper

ValidusVentus

Which is why I haven't done it and mentioned it here . It used to be common practice with some race teams (cutting them), (don't know if its still done, I had assumed all race application pads now had them from the factory) in fact Carrol Smith talks about it in his book Tune to Win. The goal is to give the (new and old) brake dust somewhere to go rather than being pushed back into the rotor material by the rest of the pad. This way more of the pad is seeing a clean/clear surface when it makes contact with the rotor. It also helps somewhat with cooling the pad. It doesn't have anything to do with gassing, which is a thing of the past.

Also I don't believe there is anything special about the material at the front or back edge of the pads to begin with so how would adding another front and rear edge do anything bad?

I started a new thread on this so I wouldn't be jacking your thread OP as this was getting a little long:
