Gents, I upgraded to this kit from Summit https://www.summitracing.com/parts/rsd-rcp79s along with a new, stock replacement MC (1.2 inch bore) with vacuum booster. Bled the lines thoroughly and the pedal is very firm, but I have pretty weak stopping power. The calipers are functioning as they should and I bench bled the MC before installing it. What gives? Do I need a smaller bore MC? Is it because I haven't broken in the new rotors and pads? At this point I don't feel safe driving it on the road to break them in. Thanks for the help.
