I thought you needed 1200 for discs? 800-1000 for drums because of how they "self energize" when the shoes grab the drum and shift on the backing plates.

what size master cylinder are you running? you can step down a size in the master to soften the pedal feel and generate more line pressure.


Also, are you using a power brake pedal on a manual brake set-up? I thought there were different pedals with different geometry for power vs manual brakes?
