Brake cable with lubricant sealing device

A brake cable, comprising:

• a joining member including a hollow body having external threads on an outer surface, an externally extended rim at a first end of the hollow body, and a channel through the hollow body;
• a fastening member including an internal space having internal threads, a hollow extension extending out of a first end, a tunnel through the hollow extension to communicate with the internal space, and an annular surface on a first end of the internal space adjacent to the hollow extension;
• a sealing assembly urged against the annular surface;
• a cable assembly including a flexible sleeve with the joining member, the sealing assembly, and the fastening member are sequentially put thereon, an annular flange disposed on an outer surface of the flexible sleeve, and a C-clip disposed at a second end of the hollow body and compressed by and between the hollow body and the annular flange wherein an inner diameter of the C-clip is less than an outer diameter of the annular flange and an outer diameter of the C-clip is greater than a diameter of the channel;
• and
• an oil tube having a first end secured to the hollow extension;
• wherein the cable assembly is disposed through the oil tube from the first end of the oil tube;
• wherein the external threads and the internal threads are secured together so that both the joining member and the fastening member are configured to compress the sealing assembly so as to urge the sealing assembly against the annular surface for preventing lubricant from leaking;
• and
• wherein the flexible sleeve includes an inner cable passing through, a gap formed between the inner cable and an inner surface of the flexible sleeve, and an opening disposed at a first end of the flexible sleeve so that the lubricant is configured to fill into the gap between the inner cable and the flexible sleeve through the opening.
