brake pad/ backing separation?
looking at my HP+ pads after 2 days of HPDE and looks like pad is pulling away from the backing plate at the ends. Any thoughts on good, bad, ignore, junk? C6 w/Z51 pkg on DBA rotors with no brake fade, bedded properly, good fluid, no cooling ducts.

Check closely and if there is an actual separation, I would not run them. Could be a major problem if they completely come apart or start to chunk on track. Contact Hawk customer service and see if they are any help.

I suspect that your usage has exceeded the heat range of your pads? Perhaps Carbotech Adam will weigh in on this issue. Otherwise, I would go with whatever feedback the roadrace members give you. Good luck.

If they delaminated, they're junk. Hawk makes a quality product; I'd contact them and send them back. They will probably send you a new or upgraded set. Is the backing plate completely parallel?

The DBA rotors have the paint marking that is supposed to change colors to white and the orange (~1000 F) is just starting to fade but still looks orangish. Green (~800F) is definitely baked white. The delamination is real, did not measure but estimate >0.008" of gap has formed at the leading and trailing edges of the pad about 1/2 inch long. Lots of material still left though. I'll have to give Hawk a call and see what they say.

I was brutal with the HP+. Up to a point they work pretty good for a compromise pad (I ran them street/track). It sounds like you cooked them a bit too much.
I'd look for a more aggressive pad.

Do you have any pictures?

Here are a couple of pics. They are both the outside pads so makes me think they are getting too hot. In photos the front pad has 0.008" gap about 3/8" deep, the other one has 0.015" for about 1/2" deep.
How do you know when it's time to add cooling ducts/ shrouds?

Are they going to be warranteed ?

When you go to the track the third time. If you like running hard.

Just got off the phone with Hawk and they said it will be covered as warranty item, have to call the retail point of purchase for service though. Their opinion was that there was likely some defect in this pad set and not heat range related. They were of the mind that unless seeing pad fade or excessive wear, it is still within temp range.
