Old Man with a Hat
IMHO beg ,borrow,or steal a flaring tool,practice using it on some scrap line you will use it again and again.It is one of the satisfying things to put a nice flare on.The less joints you have the less chance you have for a leak.$13.00 bucks at China freight might save ya $20 in atf
He better practice a lot as those cheap sets are just that. Used similar once and realized it took 3-4 tries to get one truly good flare. Now with changing my truck over to a dual master with power assist I need to make all new brake lines. I'm using hydraulic this time.
