Well I threw my PFC 01 compound pads on a few days before Daytona, and drove on them and drove to the event on them to clean off street pad material transfer off of the face of the rotor. BUT, being an idiot, I didnt properly bed them in properly on my first few laps at Daytona, and immediately began driving hard on them during my first session without regard to proper bedding procedures (series of high to low speed braking with a cool down afterwards) :bash:. I noticed in my first session that I had noticeable brake judder during threshold braking into turn 1. I noticed this through the first session, but didnt really notice it at all (at least dont remember feeling it) during the remaining 3 sessions and seemed like it went away. Could the rest of the sessions have evened out or cleaned off the uneven pad deposits?
One thing I DID notice though was a sound the pads were making against the rotor during threshold braking that I never noticed with my street pads; it was a "ssshhhhhhhhhhhhh" sound, lol, thats the best way I can describe it, kind of like the sound of a sandpaper going over the rotor, but nothing like a metal to metal sound. Is that normal with a race pad; is that just the abrasive sound it makes under heavy braking or should it be fairly quiet?
Also, for those of you who run race pads; how do you bed them in at the track? I've heard people say bed them in the night before the event, but that seems kind of pointless since the drive TO the track will scrape off the material transfer since the race pads will be very abrasive under operating temps on the street. For race pads, do you have to do a specific bedding procedure, or will a half-dozen 100 to 30 stops on the track transfer enough pad material onto the rotor that it would be "bedded" and judder-free?
I just wanted to "test" the bedding procedure on these pads to get a feel for how I would do it on track; is this how the rotor should look after bedding pads?
