Substitute for V-brake pad question (kool stop)

I've moved the rim a bit forward with the screw stops in the dropout to enable a more square contact w/ the pad, but still not happy with the wear. My Question: Is there any reason I cannot substitute the Kool Stop - Eagle II threaded post pads OR - so-called "Mountain" pads (appear to be v brake style) OR - something called "Phat pads" -something else called "supra" pads All of the above are kool-stop brand. I am soliciting opinions on this. Using a different pad will not help. The differential wear you describe is corollary to the angle of incidence of the pad on the rim, which is in turn a function of brake boss spacing and rim width. The brake pads don't move straight in towards the rim sidewalls. They rotate around the brake pivots. If the pivots are widely spaced, or the rim is narrow, then the angle between the approach of the brake pads and the rim sidewalls will necessarily be indirect. It makes no difference how thick or thin the brake pads are, or how close or distant they are from the brake arms. The dimensions of interest are only the locations of the brake bosses with respect to the rim sidewalls. You can improve the incidency angle of pad on rim by using a much wider rim, or by using a brake that has a parallelogram mechanism to bring the pads more directly towards the rim sidewalls. But just fooling around with different pads will not cause them to wear more evenly. P.S. - Your bike has far more profound problems than brake pad wear. I would think atrocious ungainly handling, and being regularly unrinated upon by dogs and humans, would be of much more urgent concern. http://www.google.com/search?hl=en&q...er%22&tbm=isch pH's bicycle lacks the problem of having a tiny saddle wedged up the rider's arse. It will also *not* dump the rider on his/her face at inopportune moments, such as Chalo himself has reported to us happening on his horsey position bicycles. -- Tºm Shermªn - 42.435731,-83.985007 I am a vehicular cyclist. |
