Abstract:
A cable actuated mechanical disc brake caliper comprising:a caliper housing; a cable guide rigidly fixed to the housing, the cable guide having a cable receiving bore extending along a guide axis which is fixed relative to the housing for axially receiving a cable; a lever arm pivotably attached to the caliper housing for pivoting about a pivot axis, the lever arm being operatively associated with a brake pad to move the brake pad between a retracted and an extended position as the lever arm is pivoted in a first direction from a non-actuated position to a fully actuated position, the lever arm including a cable clamp radially spaced from the pivotal attachment for fixedly attaching a cable to the lever arm in a select orientation relative to the lever arm at an attachment point, the attachment point being essentially coincident with the guide axis with the cable arm in the fully actuated position; and a guide surface curved about the pivot axis having 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 extending from the first portion toward the cable guide and the second portion being essentially tangent to the guide axis with the lever arm in the non-actuated position.
