I think that curbtiger has a single steel cable and he got a switch that just screwed on to the cable where it connects to the master cylinder. He said he got it from a local hydraulic place. Looked like a pretty sweet setup to me....(this was on a 450).
you can get banjo bolts with pressure switches all day long... example http://www.cyclepages.com/ProductGroupDisp.aspx?ProductGroupID=4601306 but you should be able to pick one up at your local bike shop. then just get a single line and attach it to your existing master cylinder with one of these banjo bolts and you should be good to go!
Guessing that you've got some kind of junior CB (350G/360/450 etc.) your master looks like this and the banjo bolts go as indicated. The one with the pressure sensor would go into the master. you'll delete the metal tube part on the caliper and just have a single s/s line from the master to the caliper and you'll run your brake lights off the pressure switch. hope that helps!
i'd need you to tell me exactly how long you want it and i'll orient the banjos as if i were making them for a cb750 and hope they are the same (they should be).
no difference with plain or pressure switch banjo bolt... you won't need to tell him that part. i can't help you with the length, but if no one else chimes in, it's not that hard to do it yourself... essentially you need to find a smooth path between the master and the caliper that has enough slack in it to absorb full extension of the forks, but not so much that it gets caught anywhere when the forks are under full compression.... probably the easiest way to do it would be to get some half inch vinyl tubing and plot the route that way, as it will behave approximately like your brake line, then measure the tubing. Also, hopefully the vinyl tubing will have some advertising printed lengthwise on it... this will allow you to also calculate the orientation of the banjos... i have attached a cheezy pic showing an example of a brake line which would have the banjos at 90 degrees to each other because the top bolt going into the master is horizontal and the one going into the caliper is vertical... wow, this stuff is hard to describe in words...
Perfect, that makes sense, thanks!SO I have a line on a braided cable off ebay - here's the response from the dude:Anybody have a cb450 with a straight line and feel like measuring it for me? Also, since I'm going to be using a pressure switch banjo bolt should I let this dude know?
