Brake Bleeder Thread Sealant?

[NeoJuice]

Folks,

I finally got back from holidays and had some time to work on the truck. I got the hole cut in the floor and my brother helped me bleed the brakes.

Here is a link to my old thread about the residual valve mounting.

Bleeding went smoothly and got all the air out and all nice clear fluid with no bubbles on each corner which I was very happy about and no leaks in any of the brake lines I fabricated.

Now onto the problem. All my bleeder screws are tightened up but they're leaking fluid out around the threads (I believe) on all four corners of the truck and down onto the caliper and onto the ground. WTF? I need to verify closer if it is coming from around the threads or out through the bleeder hole.

I'm worried that air might be getting sucked back into the system. The rear calipers are brand new and the front MII front calipers have never had brake fluid in them (brand new).

Should I get new bleeders? like speed bleeders? Researching online people are pro/against Teflon tape. I don't need to be going buying four new calipers.

Thank you for your time.

What are your thoughts?
