System and method for an adjustable lever assembly

An adjustable master cylinder lever assembly comprising:

• a master cylinder body including a master cylinder fulcrum;
• a lever pivotally secured to the master cylinder fulcrum with a pivot pin, the lever having an adjustment section and a grip section, wherein the grip section includes a lever finger contact portion and the adjustment section includes a slide passage in communication with an adjuster passage;
• an adjuster positioned substantially inside the adjuster passage, having an outer surface and a threaded inner passage extending therethrough, wherein the adjuster includes a spring passage for receiving a spring and a ball for biasing the adjuster in a set position;
• a piston situated inside the master cylinder body, the piston having a piston upper portion and a central piston axis extending longitudinally through the piston;
• a fixed length pushrod having a pushrod first end and a pushrod second end, the pushrod including a central pushrod axis extending longitudinally through the pushrod, wherein the pushrod second end is in operable communication with the piston upper portion;
• a slide positioned substantially inside the slide passage and outside the pivot passage, wherein the slide includes an outer wall surface that is keyed to the slide passage to substantially prevent rotation therein, the slide having a threaded outer portion for matingly engaging the threaded inner passage of the adjuster, and a lower portion secured to the pushrod first end, and wherein the master cylinder body includes a clamp having a clamp centerline, wherein rotation of the adjuster varies the distance between the lever finger contact portion and the clamp centerline;
• and
• a detent plate positioned adjacent the adjuster, the detent plate having an outer circumference that includes a plurality of notches sized to receive at least a portion of the ball therein, and an inner detent passage that is shaped to substantially correspond to the slide wall outer surface to allow for movement of the slide therethrough and to prevent rotation of the detent plate relative to the slide.

An adjustable lever assembly comprising:

• a lever having an adjustment section and a grip section, wherein the adjustment section includes a slide passage in communication with and substantially perpendicular to an adjuster passage, wherein the slide passage includes an inner wall surface with an oblong circumference;
• a spring biased cylindrical adjuster knob positioned substantially inside the adjuster passage, the adjuster knob including an outer surface protruding at least partially outside the adjuster passage and a threaded inner passage extending therethrough, wherein the adjuster knob includes a spring passage for receiving a spring and a ball for biasing the adjuster knob in a set position;
• a slide positioned substantially inside the slide passage, wherein the slide includes a slide outer wall surface that is keyed to the inner wall surface of the slide passage to substantially limit rotation of the slide with respect to the slide passage, the slide including a threaded portion for matingly engaging the threaded inner passage of the adjuster knob and a lower portion that includes a bushing passage;
• a pushrod having a longitudinal central pushrod axis and the pushrod is connected to a rotatable bushing situated in the bushing passage, the rotatable bushing including a central bushing axis extending longitudinally, wherein the push rod pivots about the bushing axis;
• and
• a detent plate positioned adjacent the adjuster knob, the detent plate having an outer circumference that includes a plurality of notches sized to receive at least a portion of the ball therein, and an inner detent passage that is shaped to substantially correspond to the slide wall outer surface to allow for movement of the slide therethrough and to prevent rotation of the detent plate relative to the slide.
