Have read mixed reviews on the manual/4 wheel discs. A smaller 15/16 bore Master cylinder seems to be recommended but haven’t heard anyone really praise their manual 4 wheel disc setup.
I run C5 calipers on 13" Cobra rotors on the front and the Jeep GC rear brakes with a 1 1/32" master cylinder without power assist. The brake pedal is stiff but it stops well enough.
Kind of feels like pedal effort is a personal opinion so I can't give a recommendation. I know I like mine but I am also working on swapping even bigger brakes on the front so never enough, right?
