Thanks for your advice.

Do you know where in the UK, can I do this rolling Road brake test?

Car recently passed its Mot with no issues.

No flat spots or juddering.

I was just going at high speed recently and braked quite hard coming to a roundabout. The car did stopped eventually, but there was a point, where I was wondering if this was "the end" for me as I was pressing the pedal relatively hard but the "slowing down" didn't match the rate I was pressing the pedal (if that makes sense).
I have also experienced this in the M5, but haven't been able to find the cause of it. It is rare.

I have also noticed that the stock pads and rotors work better warm, as hard braking has much more bite on a second application within a few seconds of a first. So sometimes when I am really going at it fast on back roads I will brake occasionally just to keep the brakes warm. I have never driven this car on a track so I can only guess that the brakes get plenty hot and stay hot.
