ABSTRACT:
A hydraulic brake includes a body defining a cylinder, a piston disposed within the cylinder, a brake lever disposed pivotally on the body, a first pivot disposed rotatably on the brake lever, and a push rod unit connected between the piston and the brake lever and including a sleeve member and a first adjustment rod. The sleeve member has a first end confined in the cylinder, a second end connected pivotally to the first pivot, and an adjustment hole extending from the first end to the second end and in spatial communication with a through hole in the first pivot. The first adjustment rod engages threadably the adjustment hole, and has an inner end in contact with the piston, and an outer end disposed outwardly of the through hole. The first adjustment rod is threadable within the sleeve member to vary a starting position of the piston.
