Appendix C: Coaster Brakes - Specialized BICYCLE Owner's Manual

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.
