Alles über Rücktrittbremsen: Unterschied zwischen den Versionen

[Note: the metal band in the photo below is only looped loosely around the chainstay, a common error. If the brake is used to hold the bicycle from rolling backward (for example, when stopped facing uphill), the brake arm will rotate upward. Then when the brake is used to slow forward motion, the brake arm will rotate downward again. Repeated motion will loosen the bolt holding the metal band, or the axle nuts, leading to failure. The metal band has multiple holes to fit different-size chainstays. Cinch it tightly around the chainstay -- John Allen]

The attachment of the reaction arm to the chainstay is vitally important. One of the most common causes of coaster-brake malfunction is failure to properly secure the reaction arm after removing and re-installing the wheel.

The trick is to treat the cause, not the symptom. Instead of immediately going for the axle nut, use a hammer to rotate the reaction arm back to its proper position. This will often bring everything back to proper adjustment with a minimum of trouble. At the very least, it will ease the binding of the axle nut, and allow you to adjust the bearing cones in the normal manner.
