Track Pad + Rotor Gone After 1 Track Day
So I posted up earlier in the week about properly embedding my pagid pads and was able to do about nine 80-15 consistent stops and then nothing but highway driving to cool them down a bit. On my first session I could tell the pads were still breaking in, but they started to feel great. Sessions 2-4 felt amazing and it seemed like all was going well. Last session of the day 5 laps in, my brakes started feeling a bit faded so I took it easy, next thing I know I get an error message from the car telling me pad wear is at a minimum...so I pull off the track. After cooling down I pull into the garage and realize I have absolutely no pad left on my passenger front, the cross drilled holes are all filled in, and it seems like some metal to metal rubbing definitely occurred from the backing plates.
The track was Homestead, and my cooling down consisted of easily 10+ minutes of driving with no braking. Pads and brake fluid was installed by a professional and not myself. After reading nothing but good things about the longevity of these pads I am curious to know how it is possible that I absolutely obliterated a pair of front pads after one track day? Any input is of course much appreciated.

I have used the RS19's on stock brakes and experienced great wear from the pads on 2 tracks that are considered quite hard on brakes and would have easily got 5-6 days out of the front pads..Even with a good race pad & stock brakes you still have to conscious of overuse and getting the brakes too hot which will result in high wear rates.Maybe you should be looking at your braking technique.

Agree something is not right. I don't want to blame the driver, maybe you have a stuck caliper or something but you should have noticed a decline in brake function. What did the driver's side look like? Keep in mind that endurance racers are going 24 hours on one or sometimes two sets of pads (the Pagid is a well known endurance racing pad), so to wear a front set out in just a few sessions is highly unusual.
I'm just back from Road Atlanta and I got repeated brake fade for the very first time (I have RS-19s, ducted/vented brakes on stock rotors and calipers) and yet, the pad wear on my fronts I'd say is 20% or so (but I only did one day's worth of driving due to a flat and a DE schedule adjusted for club racing).

some additional information i think is relevant but omitted by the OP. only pads that were obliterated were the front passenger side. Others were still good. I'd estimate approx use of 25% of other pads. I'd think this negates bad braking technique being the cause (but i'm no expert).

Yes it would!I have seen this before on Z06 Vettes when running the competition mode where it wore the pads off the primarily inside front brake and the other side looked almost new.

As jeeves mentioned it was only on one side, and I was driving with mdm on. I wouldn't say I was driving anymore aggressive then what I normally do out there, and my oem pads have made it easily 2 days out at Homestead with plenty to spare.

I called Turner to ask what they thought since I bought the pads from them, and they told me it was either some faulty bushings ( i don't think that's the case since there's only 8k miles on my car), or that my caliper stuck....but not sure that was the case since I would have realized some form of seizing while out on the track. Either way they told me faulty pads is a rarity, let alone 2 of them in one box.

Haaaaaaaaa...I would like to believe that's not necessarily the case considering there was only about 20% wear on the front driver side.

20 percent seems like a lot to use in one day also. like others were saying those pagids last 12hrs in endurance racing on quicker cars then we have but i guess also lighter.

They also have proper brake cooling which one of our issues on our cars.I still say that the differential wear rate is caused by the stability control not any fault of the pads.Once the the pad is overheated the wear rate will increase greatly compared to a pad that is at the proper operating heat range during a session.

Probably so gearhead. I still run with mdm on and think I experienced similar thing last time out on my ds2500s. But wear was even side to side for me on the front.

I had my MDM reset thanks to a passenger flailing around in the cockpit which turned it on during a session a bit ago and I was wondering why I had so much pad dust on the wheels and a poor pedal after this one session.My rear disc's had pad deposits which normally never happens.I was going fairly smoothly and the MDM was that instrusive that I feel I would never want to have it on while lapping.Rememember that I also run a Stoptech 380/355 BBK.

Sounds like MDM was killing your brakes. HMS is not a very fast track I don't see how you would wear out your pads

Which Pagid pad?
The braking program on the MDM should only activate if you are regularly achieving significant yaw in the turns, which isn't a very fast way around the circuit. That said, in my track experience, no way you can blow away a passenger-side pad set, in that short of a time, unless the caliper is hung or the pads are installed improperly. Possibly a set of stock pads at a racetrack that is hard on the brakes might disintegrate, but not racing pads.
Sounds very odd. I have gotten 8 full DE events (4 lapping sessions per event) out of my RS-19 front / RS-7 rears and they are at probably 30% remaining. My approach is typically slow-in/fast-out, so I'm very hard on the brakes. Rarely encounter fade on the two tracks I've run at (Mt. Tremblant and NHMS). I also usually run w/MDM on. Wear is very uniform all-around (four-corners). Any more info you can provide? -Brian |
