Also, they caution against using the disc, itself, to spread the calipers:
WARNING: STRAP DRIVE DISCS (pdf)
What they mean is when you're swapping pads and don't have a retractor tool handy, what some people do (including myself) is to unbolt the caliper, leave the old pads in, and firmly press the caliper towards or pull it away from the car (with the brake reservoir cap removed, of course). After about 30 seconds, this usually retracts the cylinders enough to accommodate a set of new pads.

With their strap drive system, this could bend the straps. Which would be bad.

But it looks like you don't normally need to remove the caliper, for pad changes? If that's true, then it would be a lot easier just to use the proper tool for the job!
