Appendix C

Coaster Brake

1. How the coaster brake works

The coaster brake is a sealed mechanism which is a part of the bicycle’s rear

wheel hub. The brake is activated by reversing the rotation of the pedal cranks

(see fig. 5). Start with the pedal cranks in a nearly horizontal position, with the

front pedal in about the 4 o’clock position, and apply downward foot pressure

on the pedal that is to the rear. About 1/8 turn rotation will activate the brake.

The more downward pressure you apply, the more braking force, up to the point

where the rear wheel stops rotating and begins to skid.

WARNING: Before riding, make sure that the brake is working

properly. If it is not working properly, have the bicycle checked by

your dealer before you ride it.

WARNING: If your bike has only a coaster brake, ride conservatively.

A single rear brake does not have the stopping power of front-and-

rear brake systems.

2. Adjusting your coaster brake

Coaster brake service and adjustment requires special tools and special

knowledge. Do not attempt to disassemble or service your coaster brake. Take

the bicycle to your dealer for coaster brake service.

likely it is that lighter components may be suitable for you. Discuss your

needs and your profile very honestly with your dealer.

Take these choices seriously and understand that you are responsible for the

changes.

A useful slogan to discuss with your dealer if you contemplate

changing components is “Strong, Light, Cheap –pick two.”

Original Equipment components

Bicycle and component manufacturers tests the fatigue life of the

components that are original equipment on your bike. This means that they

have met test criteria and have reasonable fatigue life. It does not mean that the

original components will last forever. They won’t.
