While fitting mudflaps today I noticed the right rear brake line was very corroded, and it has actually cracked right beneath the flare nut, how can i fix this? Is it possible to use the exsisting line beneath the rubber and fit new fittings there?

Any help would he much appreciated.

 

Only really two options.

Replace the whole line.

Or cut the line and couple together with a short piece of new line.

 

Thanks for the reply, would that be a compression fitting? I,ve read thats an mot failure? It seems there is enough of the line left for me to use if I can straighten it with out bending it.

However Im not sure what size fittings to go for.

 

10x1 swivel male not sure on internal diameter though.

 

Thanks for that, I've been searching onlone for a few hours now, Google is only showing female swivel fittings or 90 degree male fittings.

Would you know where I can get the one I need by any chance?

 

Something along these lines

You can cut and replace sections of brake pipe. Just flare the ends (one end with a internal flare the other a external flare) and use one male and one female Union to join the old with the new.

Try and use cupro-nickel pipe, it's much better quality than copper.

You will need a good quality hand held flaring tool in order to get a good flare on the existing steel pipe. Also take a very close look at all the pipes on the car, scrape off any rust muck or loose enamel as you likely find it'll need replacing in other areas too.

 

Thanks Ali-B, you're right, I've had a look at the others, the one on the rear left is corroded exactly the same, between the rubber on the pipe and the flare fitting, fronts seem to be ok, but I may as well try and fix them all.

On the broken one I think I need less than an inch of pipe as it broke right underneath the nut.

I'm still confused about the actual fittings, the original one is comletely fused to the oem brake pipe, I cant loosen it to take it out and have a look.

The link forgedmarco posted (thanks mate), I've had a reply from the seller and he states none of them are male swivel fittings.

 

Put some pictures up, I am struggling to vision what you are saying.

 

I've taken these pics from another forum

 

Ive removed some of the rubber on the hard brake line, I think there is enough for me put a new fitting on if I can bend or straighten the line in to position with out breaking it.

But I cant seem to find a male swivel fitting eitherI cant re use the old one as its completely fused to the oem flexible brake pipe that leads to the caliper.

 

You will need a double flare tool. I know that the classic Impreza uses double flare on hard brake lines, cant confirm what newage cars use, but highly doubt its different.

This is what a double flare looks like.



You will need some decent tools to get the job done, and use a good brake flaring tool, cheap ones will make a bad flare and also damage the line where it grips the line to make the flare. More damage to the line means more chance of future corrosion setting in early!

Brake flare tool (double flare, something like THIS)
Pipe cutter (get the right one for the line diameter, 3/16 or 4.75mm)
Brake line 3/16 in diameter (use Cunifer/nickel and not copper line)

Brake fittings are all M10x.1mm

You may also need a small pipe bender if you need to make some bends in the pipe.

Then you will need a brake line coupler for 3/16 pipe and with a female thread of M10x.1mm, see this image.



Then of course you will need the unions to go into the coupler and into the rubber hose coming from the calipers. Again, for 3/16 pipe and male thread size M10x1mm. See this image.



Seems like quite a bit to remember, but heres one thing that you need to make sure you do remember! Put the unions on BEFORE making the flares!

 

Thank you so much for this!!

 

Welcome

 

Also a good idea to use some PTFE tape on the coupler, unless you want to flare them like this and use a male and female union.

 

The quality of the eBay stuff wouldn't be the best but in the main picture you can see they are males and that they would obviously swivel on the pipe! Don't know what the seller is on about lol. Classic and newage hard pipes are the same.

 

can confirm this bit of information is vital.

feel like such an idiot when you forget

 

i have this tool is very easy to use and it is perfect for using on the car and with a bit a practise you can get the flares formed in a couple of minutes. http://www.ebay.co.uk/itm/Brake-Pipe...MAAOSwgkRVU1Ec

 

lol, maybe they have some scientific name for them!

 

Thanks for the advice, I've just watched a youtube video about it and it does seem very easy to use.

 

I hope I'm not going on too much about this, but I would like to get things clear in my mind before I attempt this, my car has been sorned for the past 18 months, I'm dying to drive it, so would like to run things past you guys.

I am thinking of buying this kit http://www.ebay.co.uk/itm/Copper-Nickel-Kunifer-Brake-Pipe-25ft-Roll-3-16-Metric-Male-Female-Inline-Ends-/261922260715?hash=item3cfbc886eb:g:G6gAAOSwNSxVdvb E#shId





I need to cut the oem line, put one of the male fittings on then double flare it.
Then, on that male fitting I should attach the coupler in the middle of the picture.
I then need to put another male fitting on the new brake pipe, flare it, then attach to the other end of the coupler, bend new pipe into shape, another male fitting for the flexi hose end, flare it then connect a new hose to the caliper.


Am I ok to assume the coupler in this pic is ok for me to use?

 

what I'd also do when renewing the brake lines is fit some new HEL braided lines instead of the old rubber flexible pipes

 

HI
You need to cut the broken pipe back to a straight piece and flare it , we can make you a section to go from there to the flexi pipe for you , or even supply you the parts to make your own , we have loads of fittings here

Thanks to everybody that replied, I have replaced the lines, it isnt as hard as other car forums lead you to believe. MOT is next week hopefully it will pass

 

Well done, its easy with the right tools and knowledge mate.
