11/11/2023 0 Comments Brake rivet press![]() ![]() This shortens the body of the rivet and creates a clamping force between the lining and the shoe. Pressure is applied to the rivet head to keep it tight in the shoe assembly while an installation anvil strikes the exposed tubular end of the rivet, making the walls of the tube roll outwardly and toward the head of the rivet. ![]() When the semi-tubular rivet is installed, the rivet is pushed through a hole in the lining and then through the backing plate of the brake shoe. Brake Rivet Modification & Enhancement Options: Materials / Finishes:īrake rivets are commonly produced from C1008/C1010 steel with a zinc yellow plating of approximately. In addition, the anvil and roll form design has been refined specifically for use in brake rivets to insure the proper roll-set of the rivet. Critical features are the material, hole diameter, hole depth, and the friction reducing coating to improve material flow as the rivet is set in place. The part number of a rivet is standardized with a diameter and length code which identifies the rivet needed for various lining thicknesses.īrake rivets have specific requirements which are intended to minimize or eliminate the possibility of cracking during installation. The ASME standard presents a variety of rivet lengths to insure that each lining thickness of the brake shoe can be accommodated while maintaining a hole depth that is approximately the same size as the body diameter. Another benefit of rivets versus bonding alternatives is that the brake shoe may be rebuilt by removing the rivets/sacrificial friction materials and replacing/re-riveting. Brake rivets are used as a heavy duty alternative to bonding in high load applications such-as truck brakes so that the lining maintains its position relative to the brake share during useful life of the lining.
