There's a parallel thread to this in the cyclocross forum right now, but I wanted to see some other opinions. (I don't frequent the cyclocross forum anyway...)
So. Avid Shorty 4 cantilevers on my commuter. I have them set up properly, pads and posts perpendicular to the rim when engaged, good parallel arms when engaged. The toe in is painstakingly "textbook". I have set these up as methodically as I can, and I've spent a great deal of time doing mini-adjustments to get them near perfect.
All in an effort to get rid of that front brake squeal. It just won't go away!
After my meticulous tweaking, I got them to the point where they at least won't squeal when gently applied. Anything else has ear piercing potential.
As an aside, they are mounted on an aluminum fork with a cro-moly steerer, if that matters.
Do I just need different/better pads?
Any help is appreciated.
