Nearly completed all new brake lines but I missed two female connections and the metric connections were o the MC. I wish I would have taken the advice of some members and purchased another flaring tool. I said to myself, how bad it be. After 2 hours I finally mastered the bubble flare with consistency.
I watched several videos online that were somewhat useful and used the information provided with the flaring tool I’ve had for decades.
What a mistake!
Not that I didn’t finish what I set out to do, I did but my advice to other members buy the new type tool. The old style tool needs to be super tight to achieve the bubble flare. The directions on the tool box gives a dimension to use , however going longer on the length gave a longer bubble look. The chamfering of the line inside and out along with the deburring is paramount. Followed by a good lube on the base of adapter. Extra long tubing to hold the flaring tool and wrench it down is my final tip.
