I know it is hard to believe and I'm sure you have never personally done this (), but it has been known to happen.

Although lighter, aluminum would not survive nearly as well over time in this environment. The first issue is abrasion from the shoes once any plating wore through. The second is the possibility of the parking brake being set after hot lapping (I suggest never doing this regardless of hat material). If done, there is a good chance that a very hot aluminum hat would distort and go out of round. Iron hats don't suffer the same fate as they pretty much last forever. There are some cars for which aluminum rear hats make sense, but the Nissans did not meet all of our qualifications for such.

That makes sense... thanks!

And of course I never e-braked turns in my first car, an '86 Ford Taurus, in parking lots at night. The tricky thing about that car was that it had a foot brake, which is not easy to feather when you're trying to steer and hold the release out at the same time. Not that I would know...

I would also never use the e-brake when a cop is coming up on me, but it's good to know I could continue to not do that if I got an AP kit.
