Brake line sizes?

[Moosifer85]

Hey everyone!
I am new to the forum and to motorcycles.
I bought my first bike about 6 months ago, which is also my first build. I am way over my head to say the least lol
When I bought the bike, the brakes didn't work. I finally got the front brakes cleared and cleaned of all the sludge and crap inside and got them working!
But I recently put on a set of new handlebars (about a 6 inch rise) and now my levers don't reach that high so I have to replace the front brake lines.
My idea for the bike is basically whatever I like. Let's call it a bobber/Mad Max inspired design.
I was looking at steel braided brake lines from Russel (link below)

But I have no idea if they will fit. I know the length I need is around 24-25 inches.
Someone told me to measure the inside diameter. Obviously my first question was "How the hell do I do that!?" and they never answered. Assuming cut open the old ones or measure the outside and minus a little bit.
I just don't want to drop $145+ on just brake lines and they not fit.

HELP!!!

There are countless threads here about brake lines. A search till turn up more info than you care to read. Rennsport is in Canada and should be able to hook you up for cheap. A full brake system tear down and cleanout, followed by replacing all the lines, not just that upper hose, should be considered mandatory maintenance.

Found this thread for you that may help...http://www.thegsresources.com/_foru...dian-supplier-for-making-your-own-brake-lines

Seeing as you are going with a bar that is going to give you a much longer than stock brake line length, you might want to consider making your own lines. On the 650G, you have a splitter down below the line coming off the master. Rennsport could definitely hook you up with some stock length for the two lines going to the brake calipers. You could then give them the length you need for the upper. The trick is getting the angles of the banjos setup correctly. That is something you would be able to have better control over if you are able to make your own lines.

In terms of sizes, Nessism's thread on Earl's Brake Lines outlines the sizes you need to make up your own. It's a great read regardless, and might give you enough confidence to do it yourself.
