Brake Flaring Tools
I have a couple of tool truck sets, I wound up warranting the matco one a couple of years ago, the pin that holds the one end of the flat bar busted, had the original over 25 years and flared LOTS of tube with it.... SOB if the new one isn't Taiwanese, definitely can't get as nice of job out of it as the old one. I also have the master cool hydraulic flaring tool, I never have a problem getting consistent and good flares but the only bad thing about that one other than price, is that if you're trying to flare something in place under the car it's long and can be unwieldy, there have been times I've had a hard time getting it into the spot I'm working in. If I can do it away from the car and then put the newly made lune in place it's great.
I do enough of that sort of work that I buy the 25' rolls especially when dealing with 3/16" line. Less splice joints means less cost (those fittings ain't cheap) and less joints also means less places it can leak..... And less places that need to be flared along the way to begin with.....
