Brake Improvements - Looking for thoughts

the first thing that jumps out to me is that you can't lock 'em up.

i'll be at the front of the line to say that i don't care for the ssbc systems, but that should provide adequate braking and at least lock up a little bit. did you properly bed in the pads? if not, it's certainly possible that they're glazed out.

are you sure you've got the master hooked up correctly? i seem to remember some of the "aftermarket" ones having the ports switched, especially for disc specific applications. i dunno, maybe i dreamt that while high on peyote or something.

anyway, i'm gonna throw out a WAG and say it's probably a component mismatch or there's a hard part that needs adjustment-- push rod isn't correct, pedal angle is jamming something up, etc.
