Bicycle rim brake

A rim brake for a bicycle, the rim brake comprising:

• a first brake arm, a first pivot of the first brake arm adapted to be pivotally mounted to a first mounting location on the bicycle, a first pad holder downwardly extending from the first pivot and pivoting around the first pivot in a first angular direction responsive to actuation of the brake;
• a second brake arm, a second pivot of the second brake arm adapted to be pivotally mounted to a second mounting location on the bicycle, the second pivot horizontally spaced from the first pivot, a second pad holder downwardly extending from the second pivot and pivoting around the second pivot in a second angular direction opposite the first angular direction responsive to actuation of the brake;
• a biasing member of the second brake arm upwardly extending from the second pivot and pivoting around the second pivot with the second pad holder as a unit;
• a force transfer member of the second brake arm upwardly extending from the second pivot and operable to transmit torque to the second pad holder in the second angular direction upon actuation of the brake;
• a hydraulic piston having a piston actuation axis, wherein the piston actuation axis pivots around the second pivot upon actuation of the rim brake;
• and
• a centering member adjoining the transfer member and the biasing member, the centering member defining an angular position of the force transfer member relative to the biasing member, the centering member adjustable to move the second pad holder without moving the first pad holder.
