The way I understand it, brake squeal happens when the pads grab the rim, reach max coef of friction (after they slip forward microscopically in the pad holder or due to brake arm play) then slip/spring back. The rapid, tiny movements back and forth cause the noise.
I’m wondering if holder less pads would work better in this regard. https://a.co/d/0fmE8IZP On Saturday, June 29, 2024 at 1:37:16 PM UTC-6 John Rinker wrote: > Thanks for your input Hoch.
