    Brake bleed (anti dive)

    83 Katana 1100 SD

    Powdercoated calipers, new pistons, seals and pads, braided lines.
    Same with the rear.

    I am using the pump vacuum machine.

    Ok, the rear brakes took about 5 mins to do and works PERFECT.

    Now, the fronts is a different story, What is the procedure? When I hook up the vacuum line to the bleed nipple on the calipers I'm getting pure fluid (pump brake lever 3 times and hold) eventually the lever goes spongy.
    Now, ALL I'm getting out of the anti dives is very little brake fluid and approx 85% air!
    I've gone through nearly 2 quarts of brake fluid AND still have spongy front brakes.....
    I've done many, many brake bleeds and this Katana is testing my patience!
    What am I doing wrong?

            Sounds like you are drawing false air around the bleed nipples, common problem when using a suction device. You might want to try wrapping the bleeder nipple threads with a couple of wraps of teflon tape to see if that helps you get a good seal.
