An improved brake lever assembly of the overcenter toggle type is disclosed, wherein the brake operating lever is preferably pivotally connected with the stationary mounting plate assembly about a pivot axis that is laterally displaced from the linear axis of travel of an inner cable member relative to the concentrically arranged tubular outer sheath, thereby to reduce wear of the inner cable guide means. According to a first feature of the invention, an improved anchor plate or anchor plate arrangement is provided for connecting one end of the outer sheath member with one end of the stationary mounting plate assembly. In accordance with a second feature, a ratchet and pawl assembly is provided for releasably locking the operating lever in various angular positions relative to the mounting plate assembly. In order to effect reserve travel of the operating lever beyond the normal brake fully applied position, the bow-shaped connecting link may include a plurality of pivotally connected sections that are foldable about the pivot axis of the operating lever, thereby to permit additional tensioning of the inner brake cable under emergency hand braking conditions. |
