Re: Brake line question

I always break loose bleeder screws with a standard six point deep socket. That way you grip all six sides at once not just four, and can apply clean axial force.

Then I move to a flare nut wrench to open and close the screw for the actual bleed process.

Can you tap on a slightly smaller six point socket?

And a high quality like Snapon flare nut wrench pays off. My craftsman 11mm slipped (yes, they are 11mm), but the next smaller snapon plus a few heat cycles did the trick
That was exactly what I used - craftsman 11mm flare nut wrench and it rounded the fitting nut in the very first try. I will get a couple Snapon flare nut wrench, 9mm, 10mm, 11mm and 12mm, just in case.

This was not the bleeder screw, it was the caliper-brake line fitting nut. No way to use a six points socket unless I cut the brake line to the fitting.

Oops - My mistake I should pay closer attention! Thanks for explaining.
