Rear brake pads caught on fire!

I have not had the rears apart yet so I can only talk strategy and not experience.
Dose the 928 have a drum e-brake or is it caliper actuated

drum e-brake

Yup, as Stan said, drum.

In case anyone else searches looking for e-brake adjustment, the adjustment for it is behind the e-brake handle. You access it by taking the cover off, 4 screws hold it in place. Two up top, two on the side facing the inside of the car. From there you will see the cable as it enters the body and attaches to the handle assembly via a spring and a set of bolts. Tightening the cable (pulling it further in to the car) tightens the brakes.

A properly adjusted e-brake will only take 3 clicks, when pulling up, to hold the car in place.

I always think the e-brake handle should be adjusted so it isn't any higher than the height of the seat base, as otherwise getting in and out of the car with it engaged could be damaging ..... and not to the car

So this means that the e-brake will have nothing to do with the brake cal/pads catching fire, right?

I would expect that to be true. Perhaps the only exception I can think of, would be if the e-brake caused excessive heat to the whole axle hub assembly, but that may be far fetched, and I would expect you would know whether that is possible more than I.

Maybe I missed it, but are we certain it is the pads catching fire, as opposed to some foreign matter? CV boot grease, mice bedding, etc.

There is an adjustment on the brake pedal that can cause it to put pressure on the brake unintentionally. A 928 racer (not me) made an adjustment and after a few laps on the track the car would stall when the clutch was released. Apparently he did this in two separate track sessions, where he had to be towed back, the second time flat bedded as the wheels would not release. As I recall the pedal/master cylinder adjustment can be made so that the brakes do no release as they should, so the brakes are always on....
