I just picked up a 1988 Trek 520.
I am scratching my head over how to adjust the cantilever brakes. I can't find any barrel adjusters anywhere. The rear cable goes thru a hanger attached to the seatpost bolt. I would have thought that was where the barrel adjuster would go, but no luck. The front cable goes thru the reflector mount. Again there is no adjuster. Am I missing something? I can't imagine that Trek just forgot to put on adjusters for the brakes. Did someone just take them off when they replaced the cables? If so, where should they be?
