The invention discloses a high-temperature-resistant ceramic brake pad and a production process thereof, and relates to the technical field of ceramic brake pad production to solve the problem that high temperature resistance of a brake pad cannot be estimated. The high-temperature-resistant ceramic brake pad comprises a steel backing; a noise reduction piece is arranged on the outer wall of the top of the steel backing, and a thermal insulating layer is bonded to the outer wall of the top of the noise reduction piece; and a friction material is arranged on the outer wall of the top of the thermal insulating layer and prepared from sepiolite fibers, asbestos fibers, potassium carbonate crystal whiskers, brass fibers, wollastonite, aramid fibers, aluminium silicate fibers, aluminium silicate, zirconite, cryolite, feldspar, vermiculite, graphite, antimony disulfide, talcum, mica, barite, porous iron powder, boron modified phenolic resin, open-loop polymerized phenolic resin and the like.The high-temperature-resistant ceramic brake pad has high impact-resistance strength, meanwhile the product density is low, the product hardness is low, braking noise is small, and braking duality isnot damaged.
