Hoping someone can give me some helpful knowledge here.

Short background story: replaced swingarm, didn't tighten axle bolt enough and rear brake rotated around and ripped the rear brake line.

Was hoping to just replace the part that ripped but it looks like it all may be one piece?

Can anyone give me some insight into the best (and hopefully most cost effective) way to replace or repair this part of the brake line?

If you can find someone that rebuilds lines near you... Take the line apart and get it rebuilt. Check with some shops or auto parts stores in your area.

Fyi. The caliper bracket and swingarm have a tounge and grove that locks the caliper in place. The axle shouldn't be able to move enough for the caliper to spin...

I see, will definitely double check that. Thanks for the heads up.

Will try to find a shop that can do this because replacing the whole brake line seems like a huge job with the way it's routed.

Google
hose doctor
Hydraulic lines
Car shops,
Etc and make it at a local if you want it cheaper, they are standard connections anyway ... So it does not matter if you buy it from victory or at a carshop, brakelines are al" the same materials and connections, just different configurations and lengths ....

I do think there is a pressure switch in that line, please check

Yes agree with the caliper CANNOT move even if you did not tighten that axel nut properly, the "notch & stump" are very clear ...

I just went thru the exact same situation. Its not that the axle wasn't tight enough, you probably didn't have the caliper bracket slid into the slot on the inside of the swingarm and it allowed the caliper to spin around when you hit the brakes which rips the brake hose apart.

The way to fix it is to cut the crimp fitting off of the existing steel brake line that is under the swingarm towards the front, put a flare nut on the steel brake line and flare the line using a double flare tool. Then you have to take the part of the hose that broke off to a parts store and have them match up a brake hose then you can screw the new brake hose onto the flare nut.

The part number of the brake hose that I used is: BHA38969 at Advance Auto and the flare nuts are part number:BLF 12C5.

When I get home from work I can take pictures of my fix so you can see what the final fix looks like.

It cost me a total of $22 and change as compared to $203 for a new brake line from Cheapcycleparts

The Vic Werks. I bought a set of hand grab rails from him. He might have a good used.
