Tfraser

Just curious. I noticed I have a slight leak where the brake line screws into the back brake. I'm not sure if it's just the fitting aND whether I can just unscrew it, throw something on the fitting and whatnot or if I have to replace the wheel cylinder or whatever it's called.

Might try tightening the fitting. You dont say if it is a flair or a banjo fitting. If it is a flair be sure to use a line wrench or risk rounding rounding the flair nut, if a banjo might have to replace the copper washers. Under no circumstance use a sealer its your brakes and subject to extremely high pressure.

Its a flare fitting, and I agree, try just tightening it a little bit with a wrench. A line wrench is ideal, but if you don't have one, just make sure the wrench fits tightly. If it doesn't fix the problem you'll need to replace the wheel cylinders, which would probably be a good time to redo the rear brakes entirely if they haven't been gone thru.
