A retaining formation defined on a brake lever of an air disc brake for retaining a push rod on a brake lever, the formation comprising a pinned connection 134 and a ball 130 and socket 133 joint, in which a main axis of the pinned connection is coincident with a centre of rotation of the ball and socket joint, see figures 3, 11 and 12. Alternatively the retaining formation may comprise a concave formation on one of the push rod and brake lever and a corresponding convex formation on the other of the push rod and brake lever in which the concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and brake lever, see figures 4-10 and 13-15. The concave/convex formation is preferably push fit. In another embodiment the formation may be snap fit, preferably by deformation during assembly through use of a resilient clip. |
