I rode down Cypress Mountain's 10-17% grades with my Weinmann 500 single pivot brakes without an issue. Of course, both the calipers and levers had been thoroughly disassembled, cleaned, and reassembled with new grease at all pivot points and running Kool Stop pads and new cables and housing. Even the best brakes will be sub-par with grime in the pivot points.
