On peterwhitecycles.comSchmidt Lumotec.aspOpen ↗ it says not to use the SON for disc brakes with a fork that doesn't have 'lawyer lips'. Do the Meks Carbon AII and AC supplied by HPVelotechnik have these lawyer lips? (There is also a big discussion about disc brake and quick release dangers on uk.rec.cycling)
Also it states on the page that the SON with disc brakes isn't suitable for loaded touring (or tandems) as the disc may get hot on descents and this heat may damage the magnets in the hub. Has anyone heard of this actually happening? Surely one can avoid this by using the rear disc brake to control speed on descents and only use the front brake for actually bringing oneself to a standstill?
News to me - I have the SON on my Optima Stinger which has no lawyer lips. The smart move is to use an allen-key skewer with the SON anyway, so the chances of accidentally loosening the QR are less than with a conventional one.

I wouldn't like to try that; I rarely use the rear brake at all since my rear wheel has suspension so tends to slide out if the rear brake is applied more than the front. No opinion re touring, though. I've not noticed my discs getting excessively hot on hard braking, they're certainly not getting the blue tinge you'd expect if they were really being cooked, but I know knot.
