I really hate setting up canti's :x 10mm spanner plus an allen key to hold it straight.Tighten up only to find its moved :evil:
A nightmare :shock:
Nooooo! Don't do that fit your cantis with no pads in them and get the angles all nice and symetrical and the slot for the pads standing roughly vertical
Pull your levers a good few times so you can see the arms move toward the rim roughly the same rate and that the system moves back to a good symetrical state with the slots vertical again
fart about with the dinky allen screw that acts on the little cam to get the spring balance right...
Then: Dial up about half the adjustment on your levers, then fit the pads and mounting hardware get it finger tight
Using your favourite finger push the front of the pad against the rim, making sure the pad is on the braking track of the rim all along it's length (don't use pads that someone has let get worn cock eyed, I have been known to dress XT pads with a file to rescue them)
then with your other set of finger get your ten mm spanner and secure the pad
Wind off some of you adjustment to acheive the desired clearance and that is it. beautiful superb canti performance is achieved
Pressing the forwards/front area of the pad also sets toe-in, rotation of the wheel will drag the pad when it acts on the rim. If you fit them entirely square the rear of the pad will work harder than the front... another toe-in method is to pop a bit of card (rizla packet thiscness) between the rear of the pad and the rim, no need just press the front of the pad
