Brake pipe flaring tools

Are you using a tubing cutter to cut the tube ? If so you need to debur the inside of the tubing. Just for comparison cut the tubing with a band saw or hacksaw and you will see what the true inner diameter of the tubing is compared to the lip the tubing cutter leaves. The tubing cutter also work hardens the tubing making it much harder for a successful flare. Your best chance for clean flares everytime is using a bandsaw followed by a clean up with a fine file. Please do yourself and the person next to you on the road a favor and practice till you get it right. Also, not deburring the inside of tubing can cause a tear along the sealing surface that is very hard to see and cause seeping under pressure. Hope this helps.

For goodness sake mate, please give me credit for the ability to use tools and above all the ability to be able to read.....!

Of course I de-bur and chamfer the end of the pipe before flaring, it is as I say, the quality of the tool as purchased that is the problem.....!

I may have missed it, but what are you using for lube? Also, brakes run about 1000 psi give or take...tim

If you are talking about lube used whilst flaring I use brake fluid, anything else could possibly contaminate the system...!
 
Use a good oil and then wash out the oil with some acetone or MEK. Soap and water if you are real worried. Tim
 
I flared a lot of brake tubing and have used some really low rent tools and good ones too. Get a good one-it's worth it. Mike.
 
Ok lads, This is the good oil. I've just bought off EBay, a tool for $85-00 which is modelled on the Sykes pickavant unit,

it's an absolute cracker, the only disadvantage is that it only copes with 3/16 pipe but it is compact, and fo r me, it's perfect in that my involvement is with 3/16 pipe only..!

On vehicle flares are no problem.
