    I just got it!
    Thank you for your attention.

    My clutch's master cylinder is wet. It's brake fluid, and I have to top off my brake fluid every so often.

    That all makes sense, because the cylinder is presumably filled with brake fluid from the hose that connects the brake master cylinder and clutch master cylinder directly.

    So, should I just order a new master cylinder? Or is there something else I could maybe do?

    Has anyone had this problem? I have an 05 V6.

    Thank you!

    I have not had this on my Tacoma, but I have had the same issue on my old 1986 Toyota. I have also sold autoparts in the past. I can tell you from experience the Toyota OEM part is your best bet. On my 86, I must have changed the clutch master and slave half a dozen times. They were lifetime warranty, new parts from NAPA. They were junk. Wish I had bought the OEM stuff, but I was young and poor, and the OEM was twice the price. Any of the rebuilt hydraulic parts we sold at both Kragen and NAPA were always junk too. Kept coming back under warranty. My first stop will be the dealer if I have this issue on mine.

    Check and make sure there is a bleeder screw on the slave cylinder before you jump into this. Not all vehicles have them, and the procedure for bleeding without a bleeder screw is a complete pain in the ass. You will want to research the procedure before you get into it. Also, don't allow the brake system to get air into it by letting the reservoir go dry. I have heard on this forum that you have to have a scan tool to bleed the brakes properly on these trucks.

    Had the same problem. Dripping brake fluid from the clutch master cylinder. Had to have the clutch master cylinder replaced. Had it done at the dealer for a little over 300 bucks I think.

    If you do it yourself, there should be a bleeder on the clutch slave cylinder, at least there is on mine.

    Having the same trouble with mine. Replaced under warranty in September, wiped dry, noticed fluid accumulating on the cylinder again.
    So back to the shop!
    This will be the second cylinder and TOB. Regretting the 6spd more and more all the time.
