Cantilever brakes are still the bane of my %$#!&ing (bike maintenance) existence. Only an engineer could have thought that a single nut to adjust 4 degrees of freedom simultaneously was a good thing. I marvel at the simplicity, but it means that the slightest adjustment becomes "time to start over." I'm also out of practice, though regular practice never really helped all that much.
I hope they're toed properly, because I'm not taking it for a test ride tonight. I don't think I could take starting over again.
EDIT: (7:30am) Test ride complete. They appear to be toed & adjusted correctly. I'm not THAT far out of practice.
