Abstract

<p>In recent years, due to heightened awareness of health promotion and energy conservation, demand for bicycle use for commuting, school, leisure, etc. have been increased. In sport-type bicycle, caliper brake and disk brake are common. Compared to a disk brake, braking performance of a caliper brake under wet condition reduces when driving at a high running speed. To increase the braking performance of a caliper brake of bicycle under wet condition, a brake shoe made of a fluorine-contained rubber (FKM) compound filled with rice bran ceramics (RBC) particles was developed. This article introduces the braking performance and tribological properties of the FKM/RBC shoe under wet condition from high running speed to stopping. The RBC filler possessed the characteristics to maintain the braking performance irrespective of duration of use and to reduce the wear of the shoe and rim under rainy conditions.</p>
