    Squealing Front Cantilever Brakes

    I am running D/A 7700 shifter/brake lever, Cane Creek SCX-5 Cantis and Swiss Stop combo (salmon/black) pads on a Surly CC for commuting. I had hoped that the Swiss Stop pads would have eliminated the front brake squeal...they didn't. I set the pads so they are toed in exactly right. The more front brake I pull the louder the noise. At this point I would invest in different brakes to get rid of this squeal. Any suggestions? Should I rough up the surface of the pad with sand paper and clean the rim again?

    You could...

    1) Increase the amount of toe-in (you say you've got the toe-in "perfect," but you've still got squealing, so...)

    2) Try reverse toe-in (rear-end of pads strike first)

    3) Try one of these do-dads:

    Assuming the Surly fork is drilled for the cable stop mentioned in #3. The Tektro do-dad has fixed many squealing/fork shudder issues I've had in the past w/ canti's. It also reduces the amount of toe-in required so you get better performance as well (more power).

    4) Try some mini-v brakes, such as these:
