Das 1x1 der Felgenbremsen: Unterschied zwischen den Versionen

The traditional way to adjust yaw angle was to bend the brake arms. This can lead to failure of aluminum brake arms -- see comments by Jobst Brandt. Use brake shoes with spherical washers, or replace a smooth-stud brake that does not allow yaw-angle adjustment.

Extension is the adjustment of the distance from the pad braking surface to the brake arm. Setting the shoes farther away (inward) from a cantilever arm generally increases the mechanical advantage, by increasing the cantilever angle.
