Rear Brake Line Fittings are two different sizes

[tucker0104]

So, my rear brake line is killing me. Re-did the brake no problem. Redoing the brake lines has been a big pain in the a**. Finally got the double flares down and now I can't get the fitting for the passenger side that screws in to the tee screwed in. Got all the other fittings screwed in and it took about 10 minutes. Tried that one for about an hour and nothing. I am guessing, for some reason, it is a different size. Can anyone please tell me the size so I can get an adapter. All the other sizes were 7/16"x24. Thanks for the help.

Um, it's whatever size the old fitting was. Just bring the old line into the FLAPS to match up. BTW. they make pre-cut straight lines with the two different size fittings, just need a tubing bender to get it to shape.

The wheel cylinders are bigger than the rust of the fittings. Like madpoge said, just take the old fitting with you to match it up. Or even better REUSE the old fitting
