Brake lever assembly having an adjustable leverage

摘要

A brake lever includes a bracket having a shaft disposed in the middle portion. A brake handle has a grip and an arm joined at their proximal ends. The arm includes a lower portion engaged with the shaft and includes a groove and two orifices for engaging with a barrel of a brake cable. One of the orifices is located between the other orifice and the shaft, and moves for a shorter distance than the other orifice when the arm is rotated about the shaft, such that the leverage of the brake lever can be adjusted.
