That would be a cause of longer pedal throws but I would think that the seal design would be similar and the push back the same. Larger pistons need more volume of oil to move the same distance than smaller pistons. The volume being the surface area of the piston times the distance.
The two pistons inside the MC must move a greater distance to move the extra oil required in the SRT brake system.
It is the pedal throw, I will use that word going forward, that this thread is about. We have learnt about what causes the vacuum and is the complete reverse of previous assumptions. Wiki has an informative article on the subject for those who want to expand on zip439’s post. Physics was not my strong point ever so I was lost pretty quickly.☹️

I will add to and modify post #1 as pertinent information is gathered from these later posts.

It is never to late to learn, you just have to keep the wheels in your head spinning or you are done and dusted. I would like to keep up with my grandfather 😉 Lorne on this forum, it is tough I can tell you as he is as sharp as a tack.
