As I drew a blank getting replacement hoses for the Zed, I was hoping someone on here may have a solution.
The problem is this-

Hoses have been previously repaired with an unknown paste/sealer at the join shown below-






The repair section is brass (I am pretty sure) and steel for the original pipe. As it is very close to the crimped join on the flexible section, brazing wouldn't be an option. Someone suggested silver soldering. Another suggested binning the pipes and using Earls hoses or suchlike which would be a bespoke kit I would imagine?

Anyone got a solution or would be willing to repair this pipe for me? All (constructive ) suggestions appreciated.

This is holding up the build as I don't want to fit the exhaust till this is repaired.

Thanks
Ian

Brass to steel pipe could certainly be brazed, soldered or glued with a variety of products. The result may well be as good as new, however would you be happy riding a bike with ancient / DIY repaired brake lines?

Unless you are looking to restore to concours (i.e. original spec) you would be far easier and possibly cheaper replacing with braided hoses.

repairing brake lines

buy braided lines they will look so much better

Fire some air through the hoses to clear them out and check integrity.

If they're clear and can still hold pressure, there shouldn't be a problem. . .

Personally, I would want to test them to well above their working pressure (800-1000psi being the normal working pressure) just to be safe!

It'd end up being allot of work for little reward, I hate to agree with Steve ( ) but I'd probably just replace them!

Braided lines wont expand under pressure as normal lines will and as such will increase your stopping power. If the lines expand, you've lost maximum pressure and as such will have a lower braking efficiency.

I don't think it's noticable unless you're riding balls out or on a track but it's good to know that your brakes can handle and respond to whatever you throw at them!

Probably nothing you didn't already know, but thats my 2p worth.

These are oil cooler pipes, not brake lines guys. Sorry about that. I forgot to put that in the thread title.


The brake lines are fine, having had all the olives replaced and tested.

Silver solder would be the easiest and tidiest way to braze them.

either get them brazed or take them into either hydrasun or ATR and see if one of the guys can do something for you

if your in town take it to breaking point and surely they will have something to fit mate doug

Tried Peebs and Dek. They did have hoses but the orientation of the fittings weren't the same.

CBRXX- Whereabouts are ATR?

Because of the proximity of the crimped joint, brazing may not be an option.


Thanks all.

Try Boydie he has a hydraulics company and may be able to point you in the right direction if hydrasun and ATR dont work out.

How about the radiator repair company down near the harbour. I am sure that someone got an oil cooler fixed there before.

If Boydie can't sort you out here's a link to their loccations
