    Hi guys, tryin to find some type of cable operated remote master cylinder I can use on my build so that I can run these inverted levers with internal cables. Any suggestions? Thanks

    What about just a typical motorcycle rear brake master? And as you guys can see I no nothing about brakes hahaha
     
  4. If you're going with duals this size should work. http://www.fabkevin.com/Remote Master.htm

    You could make something like it a little cheaper by using a sport bike rear nissin type master cylinder and making the brackets and linkage to make it actuate.

    You have to figure out what brakes you’re using to determine the master cylinder size. Then depending on the leverage and cable pull you get form the lever, you need to figure out the leverage you need at the linkage you make to operate the master cylinder fully and get good brake feel. Notice how on fabkevin’s piece you can adjust where the cable connects to the arm. For a reservoir, you could use just a piece of longer hose with a bolt zip tied into the end like some of sport bike guys do.

  9. i just want to run the brake lever on the handlebars, how do integrate the cylinder into the brake line? where do you typically mount the cylinder on the frame? and what do you do with the sensor. i just dont like the look of the cylinder on the handlebars, i want a clean look. any ideas?

    Kingwj I know nothing, nothing!

    I seem to remember my '74 R90S had cable actuated MC front disks. The MC was under the tank. Wish I kept that bike.

    Yes, slash 6 +7 BMW's have the cable operated MC hidden safely away from lusting eyes under the tank.like smoke in mirrors.
     
  12. Hi Guys,

    King and Hairhead beat me to it---the solution is to dig up a /7 series BMW front brake. The cable arrangement leaves the handlebars tidy, and as mentioned, the master cylinder is under the tank, out of sight and out of harm's way. Now, if anyone has a slave cylinder for a '79 R80/7-----I could *really* use it!! :banghead:

    Correct, and they're also known for their less-than-stellar performance. I have a '76 R90/6 with the under-the-tank MC, and one of the future mods I plan to do to that bike is convert to a handlebar-mounted MC. The bike just does not stop very well and, by all accounts I've read, it's because of the cable-driven MC.

    So I'd look at going with a small MC perhaps, or maybe one with a remotely mounted reservoir like the one shown above, rather than a cable-driven one.
     
  15. And if you choose not to use those nifty brake and clutch levers lemme know :wink2:
