how to measure brake lines?

[p_s]

I'm about to order preassembled Goodridge brake lines with screw-on adapters--it seemed to come out pretty well cost-wise compared to building my own.

From where to where exactly should I measure for these?

When I ordered mine for my CB650, the parts specialist at the local Honda Shop measured from the center of the circle on the banjo to the opposite center of the banjo circle. This is for a single line. I am not sure how to measure multiple lines. It should say on the page you are ordering from. Or you can just hand tight I am sure someone on here has done it and knows how to measure.

What's my line?

Hi Mr. p_s,

Great minds think alike! :-D

I just ordered Goodridge lines from Z1. I just took a tape measure, used it like a string, measured the whole line between the top of the bolts, and took off an inch at each end for the length of the banjo bolts themselves. I ended up ordering two 19" lines and one 18" line for the front of my 850. My current brake lines have very little "wiggle room". So an extra inch won't matter. I'll also be rebuilding the calipers and replacing the brake pads. Look for a new pictorial soon.

Thank you for your indulgence,

BassCliff

Appears to be many like minds.I sent my old lines away so old mate can measure them himself.Cheers,Simon.:-D

I converted to two single lines from the 3 line setup. Gives a nicer feel & it's cheaper. I ordered mine an inch or two too long.... lost it behind the headlight. With Euro bars I think you need a 31" one side & a 33" the other.

Paragon

I submitted the measurements for the GS750L to Paragon Performance and got a great deal in the bargain. I took a string and measured them a couple of times (on the bike). After that, I had my wife measure them twice to make sure the numbers agreed (they did).

Then she (architect/engineer) drew pictures of them and labeled the lengths. It's also VERY important that you note the angles that the banjo fittings are at in relationship to each end and specific curvature of the fitting itself. I'm sure there's a certain margin of error that is acceptable but the closer you get, the better they'll fit.

Thanks everyone. Makes sense now. My lines are off the bike so they're easy to measure. Buying Goodridge lines from Z1 seems cheaper than anything else and easier than building my own. (Their site says to add 1" to the hose length for each banjo fitting, but now I understand what they mean--subtract 1" for each banjo from the end-to-end measurement.)

Great info. I am about to do the same to mine. I have one other question, I was looking at the Z1 website and there are two different lengths of bolts. The 1" and 1.25". Which ones do I use? I will be replacing all the lines ,banjo fittings and bolts on the front and rear with coated SS.
Thanks:-D

I think you mean 1 mm and 1.25 mm thread pitches. Not sure what the banjo bolts are, but I'd bet they're the same. I am reusing my banjos, since they aren't a wear item and are in perfect shape.

O.K. I guess that is what I mean. I was going off the info on Z1's website. I thought they meant the length. I guess if I were to re-use mine I would for sure have the right ones.
