Abstract
A lever assembly and a master cylinder are provided. The lever assembly includes a lever and an adjuster mechanism that changes the mechanical advantage of the lever. The reach of the lever relative to a handlebar can be adjusted. Both the mechanical advantage and reach of the lever can be adjusted without tools and while a vehicle including the same is operated. The master cylinder includes a reservoir in a clamp area. A reservoir bladder fits into the reservoir. A cover encloses the bladder and includes a vent opening making the bladder at atmospheric pressure such that air can move into the bladder and out of the bladder. The master cylinder can be bled without reorienting the master cylinder. A method of adjusting a mechanical advantage of a lever and a method of bleeding a braking system without reorienting the master cylinder are also provided.
