Manual disc brakes vs power disc brakes questions

Yep, and the factory applications seem to be all over the place IMO. My cars either have or will have manual brakes, and I've used the 1 1/32" m/c's pretty much across the board. I like the extra pedal throw, and ability to modulate the brake pressure. The bigger bores, for me, we're just too stiff. I've also standardized my stuff to 2.75" calipers, and mostly 10" rear drums.
