Brake pad release: what does this mean?
I have seen a couple of references (hello @CSG Mike !) to brake pad release. That is, the way the brake pad behaves when coming off the brakes.
I'm just a noob track day driver. I release the brakes, slowly or quickly, my car behaves accordingly. Could someone explain how this characteristics translates to car behavior? Ta.

This requires a pad that has great temperature stability; most of the cheaper race pads get you the higher maximum operating temperatures novices look for after fading their stock or non-track-worthy pads, but that is typically all you get. You don't find this type of release characteristic until you're at something like a RB340, C1, or H2x grade of pad. Professional motorsports don't use these pads "because they're expensive". They use them because they give the drivers superior confidence and control, which leads to better results. Likewise, this grade of pad is universally more intuitive, allowing beginners more opportunity to learn modulation both on application and release. These pads just also all happen to have better life and thermal tolerance as a byproduct of their formulations. |

Thank you for the explanation. Where abouts do you place Carbotech's XP range?

Friction varies with temperature, so brake pedal pressure and modulation/release range changes with the temperature of the pad. Bias also changes with pad temperature differential front/rear. |
