, however 3/16 brake line is a biotch to double flare, I generally have no problem flaring 3/16 diameter brake line with the KD flare kit, just that the 3/16 pin dies are only good for about a half dozen flares before the pin breaks off the die, so I generally bulk up on 3/16 pin dies when doing a vehicle..... just practice with some various techniques to see what works with your tool, if your not having success, perhaps it's the tool your using?

When the "pin" is pinched by the flaring process it's usually caused by either not deburring the ID enough or too much tube above the clamping die/bar. On smaller tubing which can be troublesome to deburr, I sometimes will check the ID with a number drill to verify the deburring has removed all of the lip formed while cutting. I also use countersinks for deburring and have rarely broken a die even on stainless
