My pipebender won't do bends that tight, so I had to make do with a longer single curve

I’ll try and dig out a photo of mine.My pipebender won't do bends that tight, so I had to make do with a longer single curve
I bent my kunifer pipes around various sized sockets it was tough on the fingers though. I hope where you take it they are reasonably priced and worth the price of mind if your unsure but it’s not to hard to do just fiddly and can be frustrating until you master a technique that works for you.
If you decide to have a go yourself I'll help you through making pipes. I do have a flaring kit that I could sell you for a fair price. Since I've retired I find myself with 2 kits.

Top one useless. Bottom one really good.My pipebender won't do bends that tight, so I had to make do with a longer single curve
That's a fine sight. And I will be doing the same shortly on one of my cars. But it does need the rear axle out to do it in a single run.

Mine is same as the bottom one. The tightest bend is about the diameter of a small breakfast jam jar. I'll try bending around some sockets and I'll look out for one of @mrscalex "pliers".
Kunifer is a bit of a handful to bend around sockets. Especially getting a tight bend. Even with those pliers it's taken about 6-8 brake pipe fabrications to get the tightness I was looking for. They need a bit of practice to use. It's still not what I can achieve in copper but it's got pretty close.
I had a quick look on ebay as that's where mine came from. But there don't appear to be too many listings for my particular tool. This has red handles but appears to be the same. It's £15 but I seem to remember spending no more than £10 at the time.
Note mine are well built but did need a little fettling on the 'blade' edge to stop it nicking the pipe. It still does a tiny bit but it's only a scratch now.

Pardon our interruption...

This what I use (for 40 odd years), no moving parts and will bend kunifer to a 19mm diameter just using your hands.
It's a genuine Girling service tool (see part number) but I haven't found them available for a long time now.

I’ve tried to track one of those down Tony. They certainly don’t make good tools like that anymore more.

I had a close one on the Alpina, my MOT man failed it on the brake pipes he could see (and admitted he had been harsh) but was concerned about what he couldn't see. So I had him also change the metal papes front to back. When done he rang and said if ever he had felt vindicated for using his experience and gut feeling this was one of those times, the pipe running front to back and over the fuel tank, was totalled knackered and could be snapped like a twig, I was the one who snapped it when I got to the garage. The pipe was a few hard brakings from blowing.
IMO when it comes to brake pipes don't just worry about what's visible, if the exposed ones are that bad I would assume the lot is nearly as bad. It may be an expense but what's a few quid against hitting the brakes at 60mph and finding they have left the party?? Tyres and brakes, probably the most important parts of your car.

Yes this is very true. I removed a pipe that had a concealed section from my 3.0 project. I'd never actually driven the car as I brought it home on a transporter. But it was holding fluid okay. On removal of the piple and as I laid it down on the ground it disintegrated (not snapped) into 2 pieces. Incredible.
I'll see what the mechanic says. He hasn't been in touch yet so I have no idea if anything else has been discovered!
I think the advice here is tell him not to spare the replacement sections if in any doubt at all.
Yes. It's only the second time I've used this bloke after moving house and losing easy access to my previous and trusted mechanic. I'll see what he says without my involvement, get a feel for the way he does things and go from there. The Z3 is not my main car so if it needs to come off the road for a bit while I fix things properly, so be it. He's still not called but that's fairly normal for mechanics I find!
Didn't realise Stephenson's Rocket had brake pipes.....
Hi Guys,
Instead of starting a new thread I'll add to this one.
Just got a roll of kunifer, bender and flaring tool. Do I use single flare or double flare with the flare tool? Looking at what they go into such as brake hoses I'm guessing single flare?
Thanks in advance
