Is it just ME..???

Why the hell do I have such a hard time threading these brass brake lines into the hole..?? PITA... What the hell is wrong with me that I can't do such a simple connection... :BangHead::BangHead::rofl:
Which hole are you having trouble with and what brand are your parts? I've had trouble with cheap import distribution blocks not mating well with the brake line fittings. Just food for thought.
