So I just got a set of these and I love 'em but i have one question about the rear brake side lever...now that I've removed the stock brake pedal height adjuster nuts, how do you set the "play" in the brake pedal? Right now there is no play at all. As soon as I touch the rear brake pedal, it grabs...hard. I am just worried about locking it up in a corner. I put the bike up on a rear stand and of course spun the rear tire. The pads didn't appear to be rubbing without touching the pedal (i.e. no unusual drag in spinning to a stop). I went out for a ride tonight and when I got off the bike I decided to grab the calipers and see if they were warm. The rear caliper was warm...too warm to touch, while the front ones were actually cool. I understand that there are surface area differences, but what do you guys think? What does the nut at the base of the brake cylinder do?
