Hi Doctor,
My pads glazed regularly on my 300ZX, never cracked, but glazed. Every time I went up to the mountains (to our cabin) and I got a little carried away with my driving - just about every time - (Fiddletown Road in California) north of Jackson on a short curvy shortcut to 88, my brakes would smoke, and at the end of the summer I always had to have new pads because these were glazed. Don't worry about it, just install new pads and keep on NSXing.
I'm taking my NSX to the cabin soon - as soon as the snow clears, I'll report if my brake pads crack.
'99 NSX yellow, no new pads needed yet.
