Corroded brake line unions
Discussion
So I tested the flare tool I purchased on a small section of OEM steel plastic coated brake pipe and it flared no problem, so very chuffed. I removed the plastic coating, enough so the tool would grip the pipe properly:
I feel much more confident now flaring in situ, so thanks all for your help. The true test will be whether it seals or not, which I'll know in a few weeks when I replace my rear subframe.

Thanks both - surprisingly I find flaring the steel better. It’s a little tougher but once it’s finished there’s just no more give, with the Kunifer it feels you can keep on compressing.
I’ve discovered I need the long version (I couldn’t see a medium length version) of the male metric connector so I’ve ordered some from eBay. The pitch appears to be the same (1mm) as I tested the OEM connector in the connector in union I bought and it fits fine.

So I'm thinking of using the long connector rather than the short - my OEM one of the left appears to be a 'medium' size which isn't available anywhere.
Also, the short and long connectors are made from mild steel with a zinc coating, is the union made from stainless steel? Just curious.
unlikely still zinch plated I'd have thoughtAlso, the short and long connectors are made from mild steel with a zinc coating, is the union made from stainless steel? Just curious.
So I created my first “soon to be live” brake line - I bought a second hand rear axle and have just had it blasted and coated, so I can now start fixing in the brake lines/hoses.
Do you think this looks ok:
Closest it gets to the beam is about 1cm but it’s not touching it anywhere so there’s little risk of chafing. I tried to follow the pattern of the original piece but it looked a mess, so I thought as it’s only a small section I’ll do it free-hand in situ.
When it comes to replacing the OEM sections on the car I’ll be sure to use the piece I cut off as a guide.

As Steve says, just so any brackets or fixings would be coated too.
Often MOT men do not like paint or coatings on brake pipes ( other than OEM of course, but that's different )
Some still flag up the factory rubber coat some manufacturers use. It's really a cover your arse "can't check it" thing.Often MOT men do not like paint or coatings on brake pipes ( other than OEM of course, but that's different )
I still haven't gotten round to fitting the axle to my car yet, as lockdown has been eased my free time has dropped for a bit. One question I have still is what do you recommend coating the bare section of the OEM steel pipe with? To use the flaring tool I bought means cutting away a good inch or more of the coating.
