摘要： A retaining formation defined on a brake lever of an air disc brake includes a push fit/snap fit connection for releasably securing a push rod to a brake lever. The retaining formation can include a pinned connection and a ball and socket joint, and a main axis of the pinned connection is coincident with a center of rotation of the ball and socket joint. The retaining formation can include a concave formation on one of the push rod and the brake lever and a corresponding convex formation on the other of the push rod and the brake lever. The concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever. A method of assembling a brake subassembly includes the steps of assembling a push rod and a brake lever including a retaining formation such that at least a portion of the retaining formation deforms during assembly and resiles when the push rod is assembled to the brake lever to provide a snap fit connection therebetween. Another method of manufacturing a retaining formation includes the steps of providing one of a push rod and a brake lever with a concave formation, providing the other of the push rod and the brake lever with a convex formation able to receive the concave formation, assembling the concave formation and the convex formation, mechanically working the one of the push rod and the brake lever with the concave formation such that the concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever.
