    Questions about installing Ultegra Disc Brakes

    I'm building up a frame with Ultegra r8070, and I have a few questions about installing the brakes.

    The kit arrived with the hoses already installed into the calipers, and there are rubber caps on the end of the hoses. I'm assuming that they are pre-bled.

    The dealer's manual says to cut the hoses to length with a utility knife in one section, but it says to use TL-BH62 in a different section. The Shimano tool costs $60, and I already have a utility knife. Can I just use the knife? What about my Park housing cutter?

    The manual also mentions something about an Easy Joint System. How do I know if I have that? I'm guessing it's an extra collar connection on the brake line that allows me to disconnect and reconnect the brake hose.

    This is my plan:
    1. Cut the lines with my housing/cable cutter. Try not to spill too much mineral oil.
    2. Install a new barb and olive.
    3. Tighten the nut in the brake lever.
    4. Top-off/bleed the system.

    Is this right?
    I watched this video:

    Do NOT use a housing cutter. If you don't have the proper hose cutting tool carefully use a box cutter.

    While you can do this job w/o having the proper tools, having them makes things much more likely to go together correctly and not kill you.

    I prefer the Avid.
    Do you have an 8mm crows foot? A torque wrench? A bleed kit?

    Allow me to clarify: you need an open ended wrench that will attach to the torque wrench. A "crows foot" is a crescent wrench attachment that could be used on torque wrench or any other 1/4" or 3/8" drive wrench. You need a crows foot in situations when you cannot get a socket over a fastener such as when the fastener is at the end of a brake line.
