Abstract: The following embodiments relate to air disc brake tappet and brake pad backing plate with interface features. In one embodiment, an air disc brake tappet is provided comprising: a top surface; and a support member coupled with the top surface; wherein the top surface comprises an interface feature that is configured to engage with a corresponding interface feature of a brake pad backing plate. In another embodiment, an air disc brake pad assembly is provided comprising: a friction material; and a backing plate coupled with the friction material; wherein the backing plate comprises an interface feature that is configured to engage with a corresponding interface feature of a top surface of an air disc brake tappet. Other embodiments are provided.

Abstract: A disc brake system includes a torque plate having a mounting portion with an opening shaped to receive a vehicle axle and a carrier portion integrally formed with the mounting portion as a one-piece unit. The carrier portion includes an inboard leading pad support, an inboard trailing pad support, an outboard leading pad support, and an outboard trailing pad support. One or both of an inboard and/or outboard brake pad include a bearing surface engaged by a bearing surface on one of the pad supports when the disc brake system is actuated such that at least a portion of the at least one inboard and/or outboard brake pads is put in tension. At least one of the pad supports may include a slot defining the bearing surface. Methods of actuating and assembling the disc brake system are also disclosed.

Abstract: An air disc brake system includes a carrier having a mounting feature and a guide pin having a longitudinally extending relief passage. A caliper includes a longitudinally extending bore having spaced apart first and second ends, wherein the guide pin is received in the bore, and wherein the caliper is slidably mounted on the guide pin with the relief passage in fluid communication with the first and second ends of the bore. A fastener couples the guide pin to the carrier. A cap is coupled to the caliper and closes a second end of the bore. Methods of using and assembling the air disc brake system are also provided.
