The present invention relates to a method of more precisely and easily realizing cooling channels constituting a ceramic brake disk rotor. In order to achieve an object of the invention, there is provided a method of manufacturing a ceramic brake disk rotor having internal cooling channels, comprising the steps of: (a) producing loading portions 110, 210, frictional surfaces 120, 220, and vanes 300 of the disk rotor respectively through separate processes using a carbon fiber reinforced carbon-carbon composite; (b) fabricating the loading portions 110, 210, frictional surfaces 120, 220, and vanes 300 respectively produced through separate processes into one structure and (c) performing a liquid silicon-melt infiltration process for the fabricated one structure. According to the present invention, a shape of the cooling channel can be economically and easily realized, and furthermore the dimensional precision of the cooling channel is enhanced, thereby having an effect of improving the performance of the disk rotor.
