How does it feel when PSM engages?

And on the 981, after enjoying the car on a tight twisty road you can smell the rear brakes even if I was not braking aggressively, perhaps the PSM is activating the rear parking brake to help keeping the rear end under control..?

PSM has no control over parking brakes, which are mechanically activated. PSM uses the ABS hydraulic system to activate your main brakes according to preprogrammed yaw parameters.

Thanks JFP,
So if the smell comes from the rear brakes (not parking brake), then there is no need to remove the caliper to inspect the parking brake as long as the rear pads are ok is this right?

Correct; the rear parking brakes are drum style assemblies inside the center of the "hat" on your rear discs.
