So... apparently, the main brake line on a 1997 Polaris Sportsman 500 - part # 1930760 - is no longer available. I've got this unit completely tore down in my shop and it needs all three front brake hoses, so I have to do something with it. I found a brake line that looks like I might could make it work, but I can't tell about the threads. The one I am looking at is part # 1910470 and it's listed as being for a Polaris Scrambler 500 4X4 and a Sportsman 6X6. This is the ONLY hose I've found that even LOOKS like it might work.

Does any one if the threads on Polaris brake lines are pretty much standard across the board?

Yeah, I'm sorry. I should have said that.

The main brake line is a straight angle banjo bolt down to a threaded fitting on a formed pipe that threads into a splitter block.

The two secondary lines (that go to the left and right slave cylinders) are both threaded fittings on formed pipes at both ends.

Where are you? I'm sure that at least one shop on Westgate Road, Newcastle makes lines to suit.

If that is where I think it is when I did a search... I'm a bit further than that. I'm in Shelby Alabama, USA. Cool

Polaris are big in the US, not so much in the UK so if it's not available over there, it isn't going to be here either.

Saying that though, there must be custom shops you can take the original too and ask them to match it up.

Nothing stopping you taking a custom made flexible line right to the bottom.

You probably want a car mechanic to make up ridgid brake lines. They do them on cars all the time and often just build them onto the car rather than buying in pre-made ones. Copper is probably better than steel.

I made some new rigid lines for a Passat once - binned the steel and went with copper, dead easy to work with. You just need a miniature pipe bender and a flaring tool. Plus you can bend copper by hand to get a perfect fit.

One end is a flared fitting. So at least a part of that hose has to be rigid.

The hoses are only partially rigid. They are part metal, part rubber, so that they can move with the steering. I am going to take the hoses to my local NAPA (auto parts dealer) today. I think I remember seeing a sign that they can make hoses. Thanks.

No it doesn't. You get screw-on fittings of all types for flexible hose. Male or female straight threads, concave or convex.

Looking at the picture earlier, one of these looks the part (obviously, I don't know your thread size):

Only reason I can think of you'd HAVE to use a rigid brake hose is if there isn't clearance for a flexible one.

Oh, ok... I appreciate that.
