There's nothing that grease can do to hinder the pads performance, just in there for nvh..too much heat& fiction between pads & rotors on a track day for anything to "get in there " hot lapping

I'm saying I'm hoping the grease didn't melt and drip down onto the rotor surface or pad surface and cause issues. Might explain why I didn't have "such" awesome brakes in one of the sessions.

So, I took the pads out today to get a closer look at what was going on.

Turns out I was right - the grease they use on the ends of the pads to help them move around on the calipers was melting off and getting onto everything. It appears to be a kind of anti-seize, but very sticky, like tree sap.

Some can be seen here -





What's disappointing is it actually does look like the grease was getting onto the pads as seen here by the orange-ish rust colored material you see on the end of the pad, ahead of the glazed area of the pad surface -






Another pad where I had cleaned some of the dried grease residue off of the beveled edge, but you can see the glazing -







Pad straight out of the caliper on the left vs. "cleaned" pad on the right -






Backs of them from the driver's side right after I removed them, you can see the grease on the ends -





I ended up cleaning EVERYTHING out with brake cleaner since I don't have to worry about rust/corrosion here in Arizona causing any issues with normal operation, but I'm disappointed that the pads are now damaged and might not be performing the way they were designed. May end up switching to some Carbotech's sooner than I thought.

Wow those pads look terrible, all the pitting!

When I raced I used the carbotech with no complaints. Can run them right down to the back plates!
