<p>A bicycle brake device includes an arm (10) having a pivot shaft (11) for attaching to a rear fork, two caliper (30,50) having middle portions (33,53) pivotally attached to the ends of the arm (10), and having brake shoes attached to the lower portions (31,51), and a brake cable (41) for selectively forcing the lower portions (31,51) of the calipers (30,50) and the brake shoes toward each other, the calipers (30,50) may be balanced for effectively forcing the brake shoes to solidly clamp the wheel rim, and a spring (20) biasing device may bias the brake shoes away from each other when the brake cable (41) is released. A coupling device may couple the middle portions (33,53) of the calipers (30,50) together.</p> |
