Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 189 words
A brake actuator for a vehicle having a front and rear wheel and a brake assembly operatively associated with each wheel, and a brake cable extending from each assembly and coupled thereto so as to cause actuation thereof to brake the wheels, said actuator comprising a base to be fixed to the vehicle at a location enabling manipulation of the actuator by a rider of the vehicle, a manually operable lever pivotally mounted on the base so as to pivot about a predetermined axis, a braking force division member directly pivotally mounted on said lever so as to move therewith about said predetermined axis while pivoting about a second axis space from said predetermined axis but generally parallel thereto, and cable end retaining means on said member to operatively retain an end of each of said cables, wherein said retaining means are unequally spaced from said second axis so as to be on opposite sides thereof, said lever includes a handle portion and a head portion, said head portion being formed with a cylindrical opening co-axial with said second axis, and said member is slidingly received within said opening.
