Seems to me if you're trying to bed track pads at street speeds, all that extra driving in between stops will work against getting the temperature that you need. Just like running open cooling ducts.

But the concept of making the first set of stops only 'moderate' is well-taken from the point of view of controlling the rate of heat input to everything. And unlike a practice session for a wheel to wheel race where everybody else is probably doing the same thing, other drivers at an HPDE session - newly-minted intermediates in particular - may not right away pick up on what you're doing even if you stay off line to do your bedding.


FWIW, so far I've been able to get the bedding process started on the street with no extra driving between accelerating up to my braking speed and do a number of moderate stops (maybe 10 - 12?), followed by about the same number of much harder stops, and then a 10 mile or so drive out on the nearby Interstate. On the way to an event, I'll do a few harder snubs from a slightly higher speed, and the sum total of all that has seemed to be enough to put enough of a transfer layer down that the pads (Carbotech pads up to XP12) are more ready to go 9/10ths than I am.

That's with somewhat smaller rotors than what you guys have, so you should probably plan on doing more than a dozen stops in each step. As I expect to do when my own 14" 4-piston Brembo front upgrade goes on.

Like what Pete said in the other thread, it's a matter of picking something that works for you and sticking with it.
