You do not need tape on any flared fitting, brake or regular. The brake line and the fittings are different size and thread type than regular copper line and fittings. You can't mix them.
yes
Many fittings, except unions, require the use of teflon tape.
Not necessary, but recommended along with pipe thread compound.
NPT is a standard for threaded pipe and fittings. NPT stands for national pipe thread. NPT fittings are tapered thread fitting and usually rely on mechanical deformation in between the male and female fittings to create a seal in addition with teflon tape. Over tighteting may result in a leakage SAE O-ring fittings are straight fittings and rely on the O-ring to create the seal rather than deformation as in NPT fittings. Since these fittings do not depend on deformation chances of a broken fitting are virtually eliminated.
Teflon is a thermoplastic.
yes

Yes, but only if it is necessary.
No, teflon tape (and pipe dope, for that matter) should never be used on flare fittings. They are designed to seal without tape or dope, and may actually leak if tape or dope is used.
Pipe dope better solution than tape.

Teflon tape only, no joint compound. Two or three wraps is plenty... Yes agreed, teflon tape will make it easier for repairs in the future
It's real important to apply your Teflon tape in a clockwise direction which coincidentally is the same way you thread on most of your fittings.. If you apply the tape in an anticlockwise direction it will unravel as you screw on the fitting which will render it useless. To apply , this is what l find the easiest.
Taape or joint compound on the threads the same as any other pipe fitting, but not on the threads where the two halves connect.
- Teflon is very resistant to other chemicals - Teflon is a good electrical insulator - Teflon is thermo-resistant - Teflon has a very low coefficient of friction - Teflon is a non-stick material used for coatings - Teflon is a thermoplastic material
Density of POLYTETRAFLUOROETHYLENE (TEFLON):The density of Teflon is 2200 kg/m3.
