even when i loosen my brake lines a tiny bit to flush them, some air is able to get in/out around the threads of the nipple. on a painball gun, i'd use teflon tape to seal this up, but that obviously won't work for hot brakes. aluminum tape? no tape?

If you have positive pressure, can't you just close the nipple during bleed to prevent air from getting in?

with the nipple open AT ALL, there is a little pressure leaking.

Maybe I don't understand the nature of the problem. If you have enough pressure, closing the nipple before the pressure is equalized will result in no air getting in, right?

you don't understand the nature of the problem. with the nipple open at all, i can squeeze the brake pedal and some fluid will leak out at the threads. that means i don't have a perfect seal when i'm flushing the brakes. i want a perfect seal.

I THINK most brake line fittings and bleed screws use tapered threads, which by nature will have an increasing thread gap as you loosen the fitting. At first you were talking about loosening the brake line, but now it sounds like you mean the bleed screw. You mean the bleed screw, right? Anyway, with it only slightly cracked, I'm usually able to avoid having fluid come out through the threads, but it's often a fine line. I'd vote for your experience being normal and I wouldn't try to "fix" it, you might just cause problems.

yeah, i meant the screw/nipple. i too am usually able to prevent anything from coming out, but i'd rather make it that way 100% of the time.

do you think replacing the bleeder screws could help? are they the original ones?

they all leak, if you are really anal about it you can use some RTV super black, just use a little and make SURE not to get any in the bleeder hole, esp if you use speedbleeders
I've never really known anyone to use teflon tape, though it doesn't sound like a bad idea.
As far as I'm concerned though, anything that has tapered threads is designed for use without tape, so its not something I would do myself.

teflon tape would burn right up... i was thinking aluminum tape. anyway, if nobody has ever heard of this being done, it probably isn't a good idea. i could have sworn i'd seen it done before though. hrm...

Does teflon really burn up? I would think it would just kind of melt maybe and probably still do the job. You could possible get some of the plumbers putty that you brush on the threads - usually made for gas lines. It'd probably do the truck

Nah, it'd definately burn. Its not very substantial, and even the caliper would get pretty damn hot.

IDK why using teflon tape would be an issue - who cares if it burns up after the job is done? It only takes an extra minute a caliper to take the bleeder out and wrap it again. I can't think of any sort of wrap that will offer a perfect seal and not burn up over time.

I'm guessing brake fluid being flammable might have something to do with it. I wouldn't want anything that could carry a flame around my brakes.

its not like he'd be using the teflon tape to be making flammable wicks that go in every direction. he'd probably be using very little of it to seal the threads which wouldnt allow it to oxidize and burn up. teflon is very inert so i dont think you'd have a problem exposing it to brake fluid and maybe it'd melt, but your brake fluid might be boiling at that point too.

How bout me I got a fatass 3100lb car and there is a little bit of teflon on my speed bleeders?
Hell I was throwing flames at summit off my brakes (loctite literally burning off) they were so hot.
