agree with JWH20; I have a 2012 as well; same feel, clunky, it feels they are not kicking in, all of a sudden bam! they grab on. Unfortunately this is "normal" for this bike and generation it seems, unless MOB or Matt want to correct (feel free if I'm wrong).
I like using both brakes as well, but I'm already used to it, I can even almost predict, based on pressure on my lever, when will they kick in hard.
