  "textContent": "A method of manufacturing a butterfly member of an exhaust brake valve assembly. The method includes providing a metal material, machining the metal material to form a body, and drilling a through bore in a central portion of the body, thereby delimiting a first side of the body from a second side of the body that is opposite the first side. The through bore is configured to receive a shaft for pivoting movement of the body in a valve housing of the exhaust brake valve assembly. The method further includes positioning the body for a single machining operation and machining the body to form a first sealing face on the first side of the body and a second sealing face on the second side of the body. The first sealing face defines a first plane and the second sealing face defines a second plane spaced from the first plane.",
