I just got through reading the bed-in procedure on the 949 web site, as I was planning on going with Carbotech's for the upcoming season on my Miata.
Thing is, I don't know how (at an HPDE) I'm supposed to go out on track and do a bunch of near stops on track with other cars around.
Suggestions?
You can do an effective (and legal) bed-in procedure on an empty highway access road.
The purpose of bedding is to deposit a microscopic layer of pad material on the rotor. I haven't run Carbotech pads aside from those that came on my Radical, but I've bedded many sets of Hawk and Performance Friction pads. For those I've generally installed the new set a day or two prior to an event, and the first time I drive on them is leaving at dark:30 for the track. On my route to Summit Point, I wait 'til I'm on route 340, a fairly un-traffic-ed 4 lane. I do a series of braking efforts from 75-55mph , let them cool a bit, then do 2 or 3 applications from 100 or 110 down to 45 or so. Essentially what one sees in T1 under standing yellow at the beginning of a session.
At the track I may grid in the back the first session to avoid having to gorilla brake 'til they're up to temp and I've done a full full-speed braking events. Then just set about the business of converting speed and money into heat and brake dust.
I bed mine in at an abandoned new subdivision (steets only) a couple miles from my house. I have done it on the track before (but I was in instructors group and let everyone know what I was doing ahead of time). Bed them in right, and they last forever. Do it wrong and they turn to dust. That's the only thing I hate about them. Hawks were slap 'em on and get them hot on a pace lap and they'd be good.
Their procedure works perfect. I've gotten a ton of life and excellent stopping, even cold XP10 pads:
^I have no doubt their procedure is optimized for their product.
"NOTE: The proper way to bed your brake pads and brake discs (rotors) is to bed them on the racetrack, NOT on the street (excluding the Bobcat 1521 compound). "
I'm trying to think of somewhere I could actually do that, then get the car back home without having to use the brakes.
