Brake lines leaking

[BulldawgMusclecars]

I'd check the quality of the flares...if they are pre-bent lines, they are rarely an issue, but its worth checking, along with the fittings and threads themselves. You may just not have the fittings tight enough. Flares shouldn't need any tape or other sealants, but if you have an aftermarket prop valve with NPT fittings, the NPT side will need tape or thread sealant.
