Overheated Brake Calipers on a 997s

Just curious to see if anyone here has had issues with the brake calipers being damaged due to overheating ( pistons sticking due to excessive heat). I never set the parking brake when the brakes are hot... Thanks in advance.

We have got one 997-1 with red (S) calipers in the past with overheated front calipers while normal driving, after examination of the complete brake system, inclusive ABS unit, we decided in consultation with the factory, to replace both front calipers which have solved the problem.

Are there any other indicators of caliper overheating, e.g. fading or pulling? And this is the first I've heard about not setting the parking brake while the brakes are hot. Most of my driving is moderate with the occasional hard dive into a corner, but I plan to take a high performance driving course, using my car (an '05 C2S 6-speed coupe), in the near future.

Thanks for the input, I have several track hours on this car but the interesting part was I experienced no brake fade. The only symptom was the car shaking when the brakes were hot. I assumed that the rotors were warped so I took a trip to the AD to replace rotors/ pads. After further inspection the calipers turned out to be the culprit. I'm just surprised that the calipers would be cooked before anything else (brake fluid,rotors,pads) maybe they are defective... Regardless I'm switching to larger brakes. I was just curious to see if this was a common issue with the red brakes.

On the comment regarding the parking brake it's always better to cool the brakes down before setting the park brake especially after spirited driving or you'll end up with warped rotors. During normal driving it should be fine to set the brake.

How often was the brake fluid changed??

I changed the fluid once a year since new, the car has low miles. I'm almost positive that you would feel some sponginess or fade if the fluid was the issue.
