My Shimano BR-Z57 front side pull brakes. Don't brake smoothly and jerks under braking. Does anyone have any suggestions on why & how to fix this problem?
Possible issues (probably not a complete list - things I've seen)
- Dirty rims - if the rim does not provide a consistent friction surface (there is dirt that makes one part too sticky or too slick - brake pad residue etc.) you will not get smooth braking.
- Dents or blips in the rim - if the rim is wider or dented in some places it will affect braking smoothness.
- Dirty brake pads - may not affect smooth braking but clean pads will improve general braking.
I'm sure others will have suggestions.
