Hello,
While it seems obvious that the cable moves one arm towards the rim when pulling the brake lever, I can't figure out how the
other arm moves on V-brakes or dual-pivot sidepull brakes.
Some articles I read says that it's thanks to the housing, but how does the brake lever push the housing against the brake arm so as to move the pad towards the rim?
Thank you.
"
The cable housing connects to one arm, and the inner cable runs across the top of the tire to the opposite arm. When the brake is applied, the housing pushes on one cantilever while the inner cable pulls the other." (Source)
