Provided are a yaw brake lining and a method of producing the same, which relate to the technical field of macromolecular material. The yaw brake lining is mainly prepared from, by weight, the following ingredients: 40-50 parts of polyethylene terephthalate, 5-10 parts of polybutylene terephthalate, 5-10 parts of polytrimethylene terephthalate, 20-30 parts of glass fiber, 1-3 parts of anti-wear agent, 1-5 parts of lubricant, 1-3 parts of antioxidant and 1-3 parts of coupling agent. It achieves the technical effect that the brake disc is protected from damage due to its direct collision with the metal material during braking, and thus effectively guarantees the braking effect of the yaw brake.
