<p>A disc brake (10) having an anchor (12) fixed to a housing. The anchor (12) has non-symmetrical first (18) and second (20) rails. The first rail (18) has first (32) and second (34) sections each of which have a constraining surface (47, 47'; 48, 48'; 49, 49') separated from a first bearing surface (50, 50'). The second rail (20) has first (36) and second (38) sections each of which have an aligning or retaining surface (55, 55') separated from a second bearing surface (60, 60'). Carrier members (62, 62') for the first friction and second pad (22, 24) have a first projection (64, 64') which only contact the constraining surfaces (47, 47', 48, 48', 49, 49') of the first rail (18) and a second projection (68, 68') which only contacts the second bearing surface (60, 60') of the second rail (20). A spring (88) engages the first (62) and second (62') carrier members to sustain the line of tangent contact with the second bearing surface (60, 60'). The slope of bearing surfaces (60, 60') is selected such that the braking force is uniformly communicated through the first (62) and second (62') carrier members into the anchor (12) during a brake application.</p> |
