US A-bodies had 9” drums too, and they were then, and are still, pathetic.
Better braking is never a bad thing.
For the OP, I run 15/16” master cylinders on all my manual disk cars. Best of both worlds. Good feel and brake modulation without too hard of a pedal or too long of a pedal stroke.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^same here , but I cant lock them up -----------??
