Been searching my sources on the chamfer of brake line to find out what's the basis of what I know. I can find several published sources that say the tubing end should be perfectly square and flat. One thing I noticed is that these are older sources. I can find several published sources that say the tubing end should be chamfered. These are newer sources. All the old timers I know personally says it should be square and flat, pro mechanics to hobbiests. Couple young guys I know say it should be chamfered. Maybe they changed the rules when I wasn't looking ? Ill give the chamfer a try but I really cant remember having had a flare go wrong with it being square and flat.
I know there's more than 1 way to skin a cat. If what you're doing works, great. Just thought I'd bring it to the OP's attention....may help his connections. Not here to prove one way or the other.
I'm a bit of a tool junkie , So I bought the Mastercool kit to do the brake lines on my RPU. This winter when I am down in Texas I need to remember to buy a roll of 3/16" Cunifer line as I can't seem to find it here in Canada. I asked the guy at the Napa store and got a blank look till I asked him to look at Napa online. He looked at it on the computer and said, no, we don't sell that.
I haven't had any cracks in the seam in the shoulder of the flair, but the steel balloons outward there so I always take a fine file to smooth it. And I always put some anti-seize there as well.
Ordered up the Mastercool tool...went back and did alittle reading thought maybe I was missing some steps so I read up and took my tools and some s**** and set out to practice. Almost every attempt turned out like **** (and I've done a few of these without any problem) so I'll try a new tool and see if that doesn't help...haven't asked for the Cunifer at Napa yet, pretty sure I'll get the blank stare but its worth a shot ...
Screw Napa, here is a source or two. http://www.fedhillusa.com/ http://www.brakeconnect.com/product/brake-line-cunifer-copper-nickel-multiple-sizes The Mastercool is an awesome tool, all I can say is practice and you should get it.
After yrs of using the old style flaring tool i final got one from esatwood , pd. About 250.00 but is a great tool still have to use tube cutter, good brake line, d bur and you will have a good flare, take time now or rush and get brake fuild all over the place after no fun , been doing brake lines for 30 yrs. Wish i had this tool back then
