anyone notice that the inner diameter area is more burned than the outer? I find that interesting in that the outer diameter is spinning so much faster (surface area speed) than the inner. you would think that the outer diameter area would be much more destroyed. why is that not the case?

One other question, do you run them on the street? I have seen some of the chuncking on pads that were street driven (and got wet and absorbed the moisture) but never to that extreme. The RS-19s that were on my race car always wore nicely.

I've run Pagid "Blacks" RS #? ever since I started racing in 2004. My pads usually last 4-5 race weekends and ALWAYS crack as shown in the pic above. They usually have 3-6mm of material left on the backing plate when they start to come apart. I always do my best in bedding them in based on Pagids website and bring them in and letting them cool. I also always replace pads with used rotors and new rotors with old pads. Only race, never street.
Craig, based on all the Pagid logos on your post, are you affiliated with them? If so you have to see this with all of Pagid pads. I've purchased 20 plus sets of pads over the years and have never seen them last to the backing plate! I am looking for another brand as we speak.

As the Pagid site says they do have the cracks but back to the original post, no not like that...
Lasting to the backing plate: No, NEVER ever RUN them to the backing plate!
No pad used on track should ever be run that far, no exceptions.
This whole thing is assisted by proper brake size for the usage, cooling, pad management...man, there are so many variables that short of living in the car it is so hard to point out actual causes over the internet.

The truth is, the pads DO crack, chip, and chunk. Some less than others, some more. But, considering different users, different cars, and different setups ALL RESULTING IN PAD ISSUES, I have to believe at least some of the issue is with the pad.
Can we get some other users of Pagid Yellows (RS29) or Blacks (RS14) to post pictures of pads below 1/2?

For what it's worth, my RS14's ALWAYS look like this after about 50% pad usage. When I used to run Pagid Oranges, they never disintegrated like this. I ran Pagid Yellows once, and I couldn't stand the lack of braking power (compared to the RS14's), so I didn't get a chance to run it down to half pad.
I've tried it on a variety of rotors and also have rebuilt the calipers, and I still get the same chunking issue.

Heck, ive seen BMW guys install pads this way:
I hear the backing plate is pretty grippy!![Roll Eyes (Sarcastic)](https://rennlist.com/forums/images/smilies/rolleyes.gif)

lets face it folks, the heat these things tollerate is nothing short of amazing. they are like the tiles on the space shuttle. ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
anyway, if you pull them at 5-7mm, (about half gone) they are never this bad. I havent tried the blacks yet, but with the much smaller oranges, with the single piston calipers, and smaller rotors, they would become pretty useless at about 7mm. on the S4 calipers and larger rotors, they were pretty darn good until 5-7mm. any further, and you risk putting way too much heat into the calipers and the material chunks away as shown by the pics in this thread. Im wondering if the ceramic based pad of the RS14, will show any differences vs the oranges.

Thats probably what im going to be saying this next race weekend with my new RS14s and larger rotors!
I think a lot of the reason my car does as well as it does, as I havent added some of the go fast stuff that usually messes most people up!
(like stiffer springs, rear sways, 3 way shocks, huge brakes, etc etc)

Without having chunks falling off.
Have tried Pagids on most applications so far without disappointment.
Took though used Pads from a Cup and put on a GT3 once - which obviously wasn't a good combo.
