I put together a touring bike using some Shimano cantilever brakes (from ebay) that use smooth post pads. After discovering bits of aluminum embedded in the pads, I dressed up the rims and dug out the bits of aluminum and then resurfaced the Shimano pads using sandpaper. They are OK now, but I really wanted to replace my pads with Kool Stops thin line (a must have for the front brakes) salmon pads. Harris Cyclery shows exactly what I wanted, but the site says it is out of stock with no ETA. I am having a heck of a time trying to locate these items on the internet. I would like to have them before I go on tour. Any suggestions?
