Abstract
A cable actuated mechanical disc brake caliper includes a caliper housing and a cable guide rigidly fixed to the housing having a cable receiving bore extending along the guide axis for axially receiving a cable. A lever arm is pivotably attached to the caliper housing for pivoting about a pivot axis. The lever arm is operatively associated with the brake pad to move the brake pad between a retracted and an extended position as the lever arm is pivoted in the first direction from a non-actuated position to a fully actuated position. The lever arm has a cable clamp radially spaced from the pivotal attachment for fixedly attaching the cable to the lever arm in a select orientation relative to the lever arm and the attachment point. A guide surface is curved about the pivot axis and has a first portion attached to the lever arm with the attachment point essentially coincident therewith and a second portion circumferentially spaced from the first portion. The second portion is essentially tangent to the guide axis with the lever arm in the non-actuated position. A method of directing cable to a lever arm of a cable actuated mechanical disc brake described above includes providing a cable guide rigidly attached to the caliper housing defining a cable guide axis a select radial distance from the pivot axis and feeding the cable through the cable guide. The cable is attached to the lever arm at an attachment point about the select radial distance from the pivot axis. The cable is maintained essentially tangent to the guide axis as the lever is pivoted between the non-actuated and the actuated positions.
