Defeat or code out the super strong power brake pedal?
related to this, sort of, but probably not the same thing. These people are talking about emergency braking intervening with track driving. I am talking about driving in a grocery store parking lot at 5mph.

I am concerned about the amount of power brake-assist to the brake pedal pressure when driving ALL the time. I am talking about the fact a small tap on the brake pedal, compared to any other car (other than a Volkswagen, that is, who have the same tendency) is overly brake-booster-assisted and when I forget, makes me lurch fwd, with far too much stopping pressure on the brake pedal. No one needs that amount of pedal-pressure assist on the brakes. It is oppressive and unnecessary. Is there a way to tone it down or code it out for good? I do have factory carbon ceramic brakes, but that should not be the issue.
my McLaren 720s has Ceramics as well, and it requires almost F1-pressure to emergency stop and feathering the pedal is easy to modulate and predictable.

I loved the brake pedal feel on my 600LT, as you say they're very easy to modulate and be progressive with. I've not had too big an issue coming from McLaren to AMG GTR in terms of braking, it's just the bull**** safety crap Mercedes have on that annoys me!

AFAIK, this is the OEM operation of the CC brakes on the GT x, and the behavior you describe during low speed braking is NOT 'boosted' by any of the electronic nannies, but simply a mechanical feature of the CCs in this vehicle - they are super grabby, and may take additional time to 'feather-in' their modulation if comparing to/coming from CC brakes on other marks.
The CC behavior your describe is consistent with the same on my GT R
But, perhaps there may be some ?ECU Brake modulation that can be adjusted via coding - reach out to Coding Guru - BenzNinja for further inquiries
