Any one know where I could get hold of the tools and consumables to make up my own braided brake hoses ?

Please

[In-a-mini]

There are a few companies that you can get them from but the bits are not cheap. It would probably work out alot cheaper and better to order them if its special lengthes or fixings you need tell them and they can make them up for you

[minimender]

I was thinking that the projects I have to finish over say the next 18 months require 18 brake hoses and two clutch hoses so it might be cheaper to start producing them for myself.

Rally design do a good range of bits, if you try to use banjo ends wherever possible you can just swap the bolt for different fitments.

Found these http://www.frost.co.uk/productList.asp brake line forming pliers so it should be possible to get the tube and ends from somewhere.
I'll keep looking |

Link not good but click on brakes at the bottom and go to page three

Those pliers are just a small pipe bender for forming hard brake lines to shape. The tool you need for making the ends on overbraided teflon hose is a hydraulic swage former, you will not do it by hand as it needs many tonnes of pressure. I've had a quick look and the cheapest hose swaging machine I can find, which is one that you have to pump up yourself as it hasn't got a powered pump is £678.00 plus the VAT.

Your right....my eyes arn't what they were.
Abandon the idea then eh.

If you want the best of the best aerospace quality go for Aeroquip

http://www.aeroquip....C001-E-p5-8.pdf

All you need to cut the hose and fit end connections is:
Masking tape
Hacksaw
x2 adjustable spanners

Just be sure to follow aeroquips guide to the letter when it comes to insertion length of the hose into the end fitting and never be tempted to overtighten.

If you happen to know anyone in the aircraft industry / air force, ask them to blag you some as they use miles of the stuff.

There are plenty of companies about that swage hoses for hydraulic plant users etc. Speak to one of them - I got a turbo oil feed pipe made up to my own spec for less than the equivalent from Avonbar etc.
You can get the race spec alloy connectors to build your own lines but they cost lots more.

THATS the one........knew it was somewhere ...Ta

The above aeroquip link (for fuel, lube, coolant and air usage, read the text) shows that the maximum operating pressure is only 1000psi, braking systems are somewhere between 3000 and 5000 psi, if you value your life and that of others buy some already made up, much cheaper than the consequences of an accident caused by having no brakes when you need them most.

Point taken..thanks
Never looked at psi ratings

[Dan]

Most manufactured brake lines are tested to at least 10,000 PSi and good quality ones are rated for 12,000.

Good advice and well worth remembering

[Dan]

I only know that because I was looking at alternative brake layouts in the past and found a supplier of really excellent ally tube. They stated in their blurb that their tube was rated for brake systems specifically because it was tested to 10,000 PSi, I think this pressure requirement may be a legal thing.


<<edit>>

Actually I don't believe that last bit any more because I've been and looked up the specs for Kunifer (the copper alloy pipe that most of us replace our brake lines with) and it seems it's only rated to 2250 PSi. However I'm still sure that the rated pressure for flexible hoses is usually far in excess of this. Goodridge flexible hoses for automotive applications have a burst pressure of over 12,000 PSi as I said above.
