MOT Brake Testing with EPB, Haldex and DSG

Not sure this is the correct forum for this but here goes....

Have you ever wondered about how MOT brake tests are done? Rolling roads and all that.

Well, as my Superb is due shortly I wondered about how an EPB (Electric Parking Brake) would be tested given they are pretty much fully locked/unlocked devices.

Found this article on EPB MOT testing.....

So it raises a few questions especially if using an independent or non franchised Skoda dealer to do the MOT.

Are they aware of the correct methods to employ when a car has an EPB, Haldex or a DSG box? All of these could be damaged if they just try to drag the wheels on their roller tester without following the correct manufacturer/model specific instructions. Would they even be aware that any special procedure should be used?

I don't know the answers, or just how much damage is possible, but it set me off thinkig. Is it worth risking using an independent MOT centre if your car has an EPB, Haldex, or a DSG?
