ABSTRACT:
A fluid pressure apparatus for a bicycle comprises a piston, a housing with a chamber dimensioned to receive the piston therein so that the piston can move axially, and first and second fluid ports in fluid communication with the chamber. The first and second fluid ports are located so that the piston is disposed between the first and second fluid ports when the piston is disposed in a piston home position. A first positioning element moves from a first home position towards a first direction, and a first biasing element biases the first positioning element towards the first home position. A first coupling element couples the first positioning element to move with the piston in the first direction, but the first positioning element and the piston move relative to each other when the piston moves in an opposite second direction.
