Don't know how to solve your problem, camy18, but personally I'd say change your style and use that front brake....

I believe the later models have ABS, so I guess that's an option if your flush with cash.

 i use to roadrace & 883 sportie to weaken the rear brake i use to  cut & narrow some of the pad area

i seen that thread a few mths back maybe sevreal and was going to do it but ended up buying a brembo 4 spot front kit from flebay from a guy in the us it was about $300 all up you get pads with it and the bracket kit and shims looks great i did change the pads too lyndalls though which happen to be victory pads i cant say if its any good or not as the bike is still on the bench and will be for a while yet .
