that is incorrect. for the same identical amount of applied pressure the smaller the bore of a master cylinder the greater the line pressure that is generated. the larger the bore the greater amount of fluid volume that is "moved" thru the system and which coincides with the amount of calipers and size of them that the master cylinder is required to operate.
this goofy thread fails to identify and understand the "smallness" of both the rear brake rotor...the caliper....and the size of the twin pads. why is the system "wooden" in feel and small in stature? simple. to prevent unwanted rear wheel lock-up.
