Here is a picture of the pads I put on that same day, at Summit Point for the second run session. I looked at the schedule again. These are EBC Yellow Stuff pads run for 1 hour and 20 minutes between 137 and 40 MPH based on my Track mate recorder. I drove home I think that 96 miles. Total miles 241

Out of curiosity, not having done any track days, how hard do you push the car? 9/10th's, 10/10th's? Are you threshold braking all the time, or not quite pushing that hard?

I will push braking about 95% or just below where ABS would cut in. My data recorder show 1.1 to 1.2 G's on the brakes under my maximum braking.

First session @ 8/10-9/10's to warm up the car and my brain.

Second session @9/10-10/10's (late in the 2nd session is usually my best time of the day, could just as well go home afterward (based on time alone) but its too much fun!)

Thrid session @ 10/10's (the other session to set a best time of the day)

Fouth session @ 9/10-10/10's (usually working on improving a certain corner and not going for best overall times so I'm hard in some places and slightly easier in others)

Fifth session @ home on the couch. I'm exhausted!

My goal is to brake just under the point where the ABS kicks in.

As to the original question, 5/16th's clearance is fine.

Regarding the pads pictured, did you bed them before tracking?
Unless they're crumbling, I don't see any big issue.

Maybe my laptop screen lacks resolution?

I'm not sure what is wrong with the pads in the photo? From what I can see, they seem to have a lot of pad left because they are no where near worn to the holes where the brake sensor plugs in.

Yes, they look a bit "cooked" but that is normal and my pads look exactly the same with the yellow almost completely burned off and they honestly look like they've been baking in a oven! (which I suppose is about what is happening).

Am I missing something like the pad material itself is disintegrating or deteriorating or crumbling? Could it be that they may have been simply overheated and lost friction until they cooled down?

I guess I wanted an opinion about how these compared to what some of the other DE regulars see after a single day. This is not the set that went bad. That set was cut down into the holes and all cracked. They looked like alligator skin. I don't get more than 3 weekend out of a set. By that point they are with in a 1/16" of the holes.
