Abstract
A brake lever assembly for actuating a hydraulic system is shown and described. The brake lever assembly comprises a housing, a master cylinder disposed in the housing, and a master piston disposed in the master cylinder. The master piston ahs an adjustable dead band. A lever is connected to the housing and has an adjustable reach. The lever is pivotable about a first axis to adjust the reach and is pivotable about a second axis to actuate the master piston.
Claims20
A brake lever assembly comprising:
- a) a housing, and
- b) a brake lever pivotably secured to the housing at a pivot point,
- i) the brake lever including a proximal end that defines a proximal end axis, is rotatable about a pivot axis and is movable in a first plane when the proximal end rotates about the pivot axis,
- ii) the brake lever including a sloping transition that extends away from the proximal end axis at an angle, and
- iii) the brake lever including a substantially flat region that is movable in a second plane when the proximal end rotates about the pivot axis, wherein the first plane is oriented at an angle to the second plane, and wherein the sloping transition connects the substantially flat region to the proximal end.

A brake lever assembly comprising:
- a) a housing that includes a clamp that defines a centerline, wherein the centerline defines a first plane, and
- b) a brake lever pivotably secured to the housing at a pivot point, wherein the pivot point is located below the first plane,
- i) the brake lever including a proximal end that is rotatable about a pivot axis, wherein the proximal end is positioned below the first plane and defines a proximal end axis,
- ii) the brake lever including a sloping transition that extends away from the proximal end axis at an angle, and
- iii) the brake lever including a substantially flat region that is movable in a plane that is substantially coplanar with the first plane when the proximal end rotates about the pivot axis, wherein the sloping transition connects the substantially flat region to the proximal end.
