Just got some of these. Like the feel (modulation is ok, power is excellent).
I have a couple questions for other users of these:
1) Regarding the centering adjustment. My brakes came with two types of washers, a thicker one and a thinner one. Should I use one or both of them, and where should a place them between the fork and the brake? What has worked for you? I've been using both washers (thinner closest to brake, thicker one against fork/frame), and centering is ok if I also use the side adjust bolt, but I'm wondering if there are better/easier methods for centering in terms of washer placement.
I think the washers are just to give adequate frame clearnce. So I am using 1 washer in the front, and two washers in the rear. I don't think the order or number matters except to give adequate clearance. Use at least one though so it will hold on to the frame at center.
Center the brake as best you can and tighten the fastening bolt, which will cause the serrated washer to "bite" into the frame. Then, use the small adjustment bolt for fine tuning. I also have one of the Park brake adjustment wrenches if I occasionally need a more dramatic recentering (just grab the flats on the main brake bolt and twist it to center.)
2) Are you torquing the pinch bolt to a certain Nm reading? I don't want to overtighten and smash the cable with the smaller pinch bolt, but I also don't want the cable to slip from an insufficiently tightened bolt. Is hand tightening enough?
I use a small crescent wrench and a hex key (what is it ? ...2 mm ?) Anyway, the guys who design screws and wrenches are diabolically clever in choosing the diameters and lengths of the hex keys so that the hex key will start to bend an be overstressed-looking at about the right maximum torque on the bolt. So I would say "tighten firmly" but use common sense. I don't measure, but I would guesstimate that it is about 2 N-m. I have never had a problem with loosening or breaking the cable.
