The invention relates to a disc brake assembly and a manufacturing method thereof. The disc brake assembly is provided with one or more rotor discs provided with annular friction surfaces and capable of performing axial movement, wherein the rotor discs are arranged between an annular piston in an annular pressure cavity in a housing and an annular reverse action plate attached and connected to the piston in the axial direction. A friction sheet is arranged on the reverse action plate and is further arranged on an annular reverse action disc located between the rotor discs and capable of performing axial movement. A positioning plate is arranged between the piston and the rotor discs, poppets capable of performing axial movement are arranged on the positioning plate, and each poppet is provided with a friction sheet for being in contact with the adjacent rotor discs. Springs on the poppets enable the poppet sheets, the rotor discs and the friction sheets to be axially biased together, and accordingly a required initial braking torque is provided. After a fluid pressure is exerted on a piston cavity, the housing enables the positioning plate to move so as to move the poppets, and accordingly the braking torque is released.
