Abstract

A bicycle brake mechanism includes a body located above a front wheel and a pivotable member is pivotably connected to the body. A hydraulic device is connected to the pivotable member so as to pivot the pivotable member. Two brake arms are located on two sides of the rim and two respective first ends of two link units are respectively connected to two ends of each of the brake arms. The two respective second ends of the links units are connected to two ends of the body. One end of each of the two brake arms is pushed by the pivotable member when the hydraulic device is activated so as to pull the pivotable member. The two link units make the two brake arms to be simultaneously moved to stop the rim.

Claims7

Dependent claims

A bicycle brake mechanism comprising:

a U-shaped body adapted to be located above a front wheel and two slots defined through two respective tops of two ends of the body, a pivotable member having two legs which extend through the two slots, two pins extending through the two legs and pivotably connecting the two legs to the body;
two brake arms located at inside of the body and movably connected to the body by two tubes, each brake arm having a brake pad connected thereto, the two tubes being in contact with the pivotable member so that the two brake arms are moved when the pivotable member is pivoted, two link units pivotably connected to two ends of each of the brake arms and the body so that the two brake arms are moved simultaneously, and
a hydraulic device including a hydraulic pipe connected between a brake lever and a connector which is connected to the body, an operation cable movably extending from the connector and pivotably connected to the pivotable member.

Dependencies are inferred from the claim text.
