Where would you use Teflon tape in a brake system? It's inert, anyway.
I only do a gravity bleed on a known good system. In my experience, it simply doesn't provide the velocity to get junk or air out.Couple panic stops today (florida is lawless) and it still feels good.
Anyone gravity drain before? Ive got half a bottle left and id rather bleed the brakes again (just incase) then to let it collect water on the shelf. My wife is tired of helping haha.
