Installing SS Brake Lines, What angles?

[danny01975]

I am looking at installing SS brake lines on my 82 GS1100. Currently has stock setup. I was going to go with the ones from Z1, but I'm not sure of which banjo fittings to go with. Anyone else here already replace theirs with ones from Z1 and can let me know the lengths and fittings used?

Measuring the length is no big deal. I'm just not sure how to determine the correct angle on the fittings. So, if nothing else, just the fitting angles would be super helpful!

Match the angles you have now. Most will be straight (0*) or slight bend (20*).

When I ordered a set of Spiegler lines for my 850G I called and spoke with the sales person. It's been several years and I forgot who sold them. Anyway they knew the lengths and angles.

As a crude tool there's a protractor app on my phone that will work to determine angles based on the position of the phone. Maybe hold the banjo bolt level and use the edge of the phone for reference.

That's the problem I'm having now. I don't have a way to match the angles and there are 8 different ones to choose from. While still useful, the parts fiches don't show the angles or banjo connectors individually. Burque73 below recommended a protractor app which may get me close enough to determine what I need.

They are all going to be a straight bend. Either a 0* (straight) or 20* (Slight bend). I don't think you would have any that are 45* bend - these should be pretty easy to eyeball if you do.

Consider a double banjo bolt at the right caliper with a loop over the top of the fender & eliminating the splitter block under the triple tree. It's a cheaper option and simple with the angles needed if you don't care about originality.

Note that you can also fit the twinpot calipers and CBR rotors to that bike if it's performance you are after.

Pic 1: Bike 1, stock MC and calipers. 20 degree bend at the MC, no bend at the calipers (pic came out fuzzy so not posted but they are just stock calipers), uses stock splitter.

Pic 2: Bike 2, CBR caliper system with stock MC. Uses a double banjo with two separate lines all the way, done by previous owner. Funky dirty white cloth covered lines that I painted gray, meh.

Pic 3: the CBR brakes. I just bled the system today, last thing on a full GS1100E assembly (well, no motor work). Special brackets and spacers to move discs out, no idea where they originated, might be tricky to find. Will find out how they work soon.

I did some quick measuring with a protractor tool on my phone and came out to 23 degrees. So 20 is probably right. And the others were straight, as you suggested.

Thanks for the pics! That helps allot! I saw suggestions for running two lines from the MC directly to the calipers. Is that better / worse than doing what salty_monk suggested, running one line to the right caliper, then a loop over to the left? Also, is there an advantage to eliminating the splitter block and running two lines instead?

Glad to be of service.

I think if you are building the lines yourself, which I've done with Earl's, then salty's way would be fine. Personally I'd do a single line to the splitter like stock, and then separate lines. It keeps all the routing simple and clean. I don't know why the PO did the two separate lines but I'm to lazy and cheap to change it, as it works.

There's tutorials on here about building your own. But it takes time. If you buy a kit, it should just fit and be easy, from MC to splitter and then down to calipers. Probably easiest and cleanest IMO.

Here’s how i did mine

All of my bikes have them and I buy from Raymond Chan....he would have the measurements from my purchase...he knows me....Trevor Franklin
