ABSTRACT:
An improved hydraulic brake apparatus for bicycles wherein brake pads are operably associated with both the front and rear wheels of the bicycle and manually actuated by a brake handle to enforce braking conditions. The improved brake apparatus includes an immersed valve member in a vertical hydraulic mechanism designed for simple and efficient performance, an improved linkage that provides increased mechanical advantage, self-adjusting retraction screws that allow for customary pad wear, an improved housing clamp for mounting the housing to the handlebar and an enhanced hose fitting that is likewise designed for simple, effective performance.
