When I changed out the stock pads on my Shimano XTRs for Kool Stops, I had to use a nickel as a spacer to get enough toe-in to get rid of squeal. With the stock pads, a dime was enough. Recently, I changed out the XTRs for the Tektros that Riv had. They are of course much wider than the XTRs but I set them up with the pads against the arms & used the suggested toe-in at the front & didn't bother at the back. Zero squeal. No change of rims (Mavic A719 rear; Fairlane front). I think it's the pads having to be set out from the arms on V-brakes & low profile cantis. A friend has Vs on his touring bike & he's never been able to get rid of the squeal.

I've had similar issues with v-brakes on my touring bike and a friend has avid shorty's on his cross bike and they constantly squeal. Commonality here was that they were all using narrow rims (Mavic Open Pro's). I haven't tried this myself yet (my touring bike was disassembled until last weekend), but I would try a thicker pad, one that didn't need to be spaced so far from the brake arm, such as the Kool-Stop Supra 2: http://sheldonbrown.com/harris/brakeshoes.html#supra2 On Jan 29, 6:52 pm, Ray <r.sh...@sbcglobal.net> wrote: > Yes, I know it's been worked over, ad nauseum, but I still have the > squealing brakes on my QB.
