I went and did about 15 stops from 20 MPH or so to zero and then several from 40 MPH to zero and then several from 65 MPH to zero. I let the pads cool off and then went out and did a couple of stops from "fast" to zero and let the pads cool. When I did the first race I did several laps with easy braking and then I used then hard. That seems to have worked well.

I always try to break in any pad just like John says.
However, no matter how much break in attemps I make, it always seems that I loose my pads once the first time they get really hot on track. after that everything is fine. I've had the same lost pad experience with KFP's, RS4's, and any pad I've ever tried. for street work this never happens, but for true track work the first time I really get on the pad hot the pedal starts to go and the stopping ability is reduced. I've learned to always break pads in under practice conditions with a clear track and a run off strategy planned. After one corner of that and an easy cooling off lap everything is fine! brant |

the link implies to me that anyone with "performance" pads (i think race/street prolly describes the kinda pads that I and most others have: "PRB" from pelican) needs to do this to bring the brakes up to real potential. So does it benefit someone to do this for a non-track car? Is there a down side? High pad consumption is a price I would pay for optimized performance....
