The 'E' Type Forum

The next part of the rebuild of my 1968 OTS is the replacement of the brake lines with 3/16 Kunifer. Regarding the shape of the terminal ends, should this be double flared or bubble flared ??? My " cheapie" flaring machine does both.

Thanks for your help

Mike

You asking the question worries me Mike. You obviously have to match the fittings concerned and be able to work out which is which.

No offence Mike, but how many brake lines have you made before? These are quick cars. You sound like a pre-formed kit might be more up your street if you think a cheapo tool and modest/no experience is enough to do an E-type right first time.

Take care and every success, whichever option you choose.

Hi Peter

Thanks for your reply. Sorry I should have been more specific with my enquiry. Some of the end fittings are quite obvious, for example an end fitting to a flexible brake hose, this can be easily seen and the required end fitting made. I was thinking more of which end fitting should be used on for example a three way union, where I cant see the inside of the fitting ( bubble or double flare )

Again thanks for the input and thanks for all of you valuable input on the forum

cheers

Hi Mike.....a universal double flare will cover everything you need for cunifer......however depending on you cheap tool ive tried some in the past that are not upto the job giving unreliabke results.......very good at producing reliable consistant resukts is one of these... http://www.automec.co.uk/products/unive ... m-by-oakes the company also sell all the fitments you need.....give them a call they will also explain all there products

Hi Mike,
This tool is also very pleasant to use

The brake line is not a joke. You must have the good tube and tools to built something secur.

Good luck with a cheap brake tool working on kunifer pipe
It is not as easy as working with copper
Automec supply a kit for etypes with all pipes made up for less than the cost of a decent brake flaring tool.
I really don't know why you would bother making your own?

Because if you are a bit OCD like me, you may want to run the pipe through a straightener which you can't do with the ends on. Plus heaven forbid you damage one piece of a pre made kit, can you buy just one piece.
What if you've upgraded the brake system and need custom lengths and fittings?

All that aside and especially with cunifer, as mentioned above, a good quality flaring tool and some previous experience are a must.

I used one of these to make my pipes with:

It can make excellent single and double flares in Kunifer Copper Nickel pipes.

Most are single, but some are double on the E-Type.

Paul

Hi Paul.....where are you useing single flares for cunifer........my understanding is that single flares are not acceptable for high pressure braking systems as the flare is thin and liable to crack.....the double flare uses more material and much stronger

Hi Steve,

Off the top of my head I cannot say where I used single flares on the E, as it was about a year ago now.

I have made up brake pipes for several different cars, so it is possible that I made them for one of them.

Where did you get the information that making up single flares in copper/nickel was not acceptible?

Paul

Hi Paul....just search on line.....but also from http://www.automec.co.uk brake pipe,fittings and tool suppliers..... when i first got my flare tool i went to visit and had quite a chat with there tech guys about what i shoukd be useing for my MGC and E type.....cant say its 100% correct but its what ive been led to believe

Some of those cheap flaring tools are just horrible. You'll be lucky to get a good flare.

Agree with you Hugo !

Guys
Thanks for all of the advice, the " Cheapie " tool has been binned and one of the tools recommended by a previous poster has been ordered. Thanks again

Mike
