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.
C. Understanding components
It is often necessary to remove and disassemble components in order to properly and carefully inspect them. This is a job for a professional
bicycle mechanic with the special tools, skills and experience to inspect and service today’s high-tech high-performance bicycles and their
components.
Aftermarket “Super Light” components
Think carefully about your rider profile as outlined above. The more you fit the “shorten product life” profile, the more you must question
the use of super light components. The more you fit the “lengthen product life” profile, the more 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.
