    No pressure in the front brake since I put the line extender on after the bar risers. Guess plan A will be to wrap the lever closed overnight and hope the bubbles rise up. I remember someone on the list saying you don’t necessarily need to bleed with the vacuum hoses but can simply open the cap and gently work the handle till bubbles rise out. Am I remembering this correctly?

    there is my way, attach bleed tubes (clear vinyl) long enough to reach the pump level from the bleeder screws. open cap, fill the reservoir, start pumping and you will see air bubbles rising through the clear lines with some fluid escaping them. just remember and check that your reservoir is always full... You can route the lines in the reservoir so you will lose no fluid but I prefer not to...

    Trying to avoid bleed tubes. What’s the basic solution without them?

    Tying the handle down overnight helped about 50% but still a bit soft. If I open the nipple near the front reservoir and pump the handle until pure fluid and no bubbles, this will solve it?

    Probably, but you need to build up pressure before opening the bleeder valve. It is a long process to do that way. I typically pump the lever until I get pressure (3-5 times, then hold the lever firmly as I open the bleeder. Close the bleeder before the lever loses pressure (before it gets to the hand grip). Then repeat over and over again. I've also found that pulling really hard on the lever will oftentimes get bubbles to rise into the reservoir.

    Aghhhhhhhh, I may as well buy a bleeder kit. On Amazon got about $20 bucks. Thanks for the advice.

    The damn thing healed itself. While the bleeder kit was on the way I gave the handle a few more vigorous pulls and five or six good size bubbles floated to the top. Now the lever is tight as a drum.

    Rox nock-offs from Amazon. Bought them last fall and they aren’t listed anymore. They seemed high quality and have worked out well so far.
