COASTER BRAKE HUB
For the coaster brake to operate properly, it must be centered and
securely attached to the frame. The coaster brake arm is bolted to
the arm bracket on the frame. A loose or detached coaster brake
arm will cause serious damage to the braking mechanism and the
internal parts of the coaster brake. Inspect the brake arm bolt
regularly.
