  "textContent": "An oil drain combination for a brake contains: a wrench and a draining assembly. The wrench is a ratchet wrench. The draining assembly is connected in the wrench and includes a coupling shaft, a fitting member, a first joining tube, and a fixing member. The fitting member is rotatably accommodated in a drive head of the wrench. An axial line of the fixing member extends from the first segment of the fixing member to a second segment of the fixing member and insects with a central line of the coupling shaft perpendicularly. The first joining tube has an accommodation orifice and an axial orifice. The coupling shaft has a blind orifice and multiple radial orifices. The fixing member has a first connection hole communicating with a second connection hole.",
