Abstract
Described herein is a hydraulic brake lever assembly that includes a clamp member that includes a handle bar opening, a housing extending outwardly from the clamp member, and a lever pivotally connected to the clamp member. The housing includes a cylinder defined therein that includes a master piston. The clamp member and the housing cooperate to define a reservoir having a first portion and a second portion. The first portion is substantially located in the housing and extends substantially parallel to the cylinder and the second portion is substantially located in the clamp member between the handle bar opening and the lever.
Claims9
A hydraulic brake lever assembly comprising:
- a clamp member that includes a handle bar opening that defines a clamp axis,
- a lever pivotally connected to the clamp member,
- a housing extending outwardly from the clamp member, wherein the housing includes a cylinder defined therein that defines a cylinder axis and includes a master piston therein,
- a push rod having a shaft operatively associated with the lever and a head operatively associated with the piston, wherein a first plane is defined at a point where the head and the shaft meet, wherein the first plane extends approximately perpendicular to the cylinder axis, and wherein the clamp axis and the cylinder axis extend approximately parallel to one another,
- wherein the clamp member and the housing cooperate to define a reservoir having a first portion and a second portion, wherein the first portion is substantially located in the housing, wherein the first portion includes front and back walls that partially define the reservoir and extend approximately parallel to one another and approximately parallel to the cylinder axis, wherein the first plane intersects the front wall and the back wall at a point where the front wall and the back wall extend parallel to one another, and wherein the second portion is substantially located in the clamp member between the handle bar opening and the lever, wherein the cylinder axis is bisected by a second plane,
- wherein the second plane bisects both the cylinder and the lever, wherein the second plane is offset from the clamp axis.
