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.

Take the pads out & look close, if you like take a pic & post. I have used up a lot of hp+ and never had separation, not to say it couldn't happen.

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?

Normal for HP+ pads, which are good for one track event, then toss them

I guess this means it is time to move up to a higher heat range compound? Figured, I'd see pitting of the pads like happened with the factory ones.

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.

you cooked them and they are not really a track pad for the abusive.

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?

Dirty Howie

I'll have to go check and make sure I don't have gaps like that too.

Are they going to be warranteed ?

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

Well, this was my 2nd & 3rd days this year, so will have to add ducts to the to-do list. Got some SS pistions and hard lines last week and was going to rebuild the calipers already.

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.

Good to know
