  • Patent number: 8997943
    Abstract: A bicycle brake apparatus includes first and second brake arms. The first brake arm includes a first brake arm mounting portion for mounting the first brake arm to a bicycle frame member, a first brake pad mounting portion, and a first control interface portion. The second brake arm includes a second brake arm mounting portion for mounting the second brake arm to the bicycle frame member and a second brake pad mounting portion. A synchronizing link communicates a synchronizing force that arises from one of the first brake arm or the second brake arm to the other one of the first brake arm or the second brake arm so that the first brake arm and the second brake arm move in synchronization.
