Brake line question - will these fit?

[Jeff Elliott]

Replacing all my rubber lines with braded lines gifted to me by the PO. The drop line to the top of the front axle from the frame seems to have a different connection than the stock line. The stock line is a concave flare while the new line seems to be more of a compound flare.

Can I use the new line? It doesn't seem to screw completely into the connector on top of the front axle like the stock unit did. FWIW, these were just lines in a box of parts - no box or instructions.

Thanks!

I wouldn't use the new braided line. It needs to have the correct fitting to get a tight seal. You could also mess up the fitting on the axle, which is NLA, afaik.

I would have thought the same BUT metal tech has lines on their site for an 80 series and a close up enough picture for me to see the fitting... it's the same as what I have on my new line:

That is odd. You have much less sealing surface compared to stock. I went with extended length Toyota lines.

Here is what stock is for the frame to left front axle for my LX450.

The Toyota lines are on the order of $15 each ordered from Japan or Dubai. I do not know a good reason for using anything else.

Well, these were free so I suppose that’s my rationale if they fit. I also have the truck on the rack as I thought I had everything I needed to do the job. If I need to order more parts, the truck has to sit there until they arrive which is a pain.

In searching some more, it appears Slee's kit uses fittings like the ones I have:

I think I'm going to give it a go. It'll either leak or it won't. Will report back. Feel free to stop me if someone knows more than I do at this juncture.

I can't comment on your lines, but I can say that the Slee lines fit like a glove on my '94. No issues.

Update: All installed with no leaks. Gonna call this a success! Thanks for the input.

I'm replacing some lines on my 450 and i'm looking to this also . The new line in your photo looks like a bubble flare not a double flare . There is a big difference in the 2 . If you look at the old one its inverted cone shape and thats what the union fitting that its screws into tightens up to . If you were to put the the new tip and butt it up to the old one you will see it it kind of fits together . The union piece on the truck you are screwing the line into kind of looks like the tip of your new connection . Its like the union has a male center piece and old inverted or double flare tip is the female end and when you tighten it up they fit together all the way around the length of the taper . If you try to tighten up the new male tip to the union male tip the only part of the metal that are touching together are the very tips of each end so you are only talking about 1 tenth of a mm contacting each other . Here is a close up photo of the inside of the union on the inside . You can see it has a male tapered piece sticking up from the center . Thats why the other end has to be a double flare or inverted flare . I am not a mechanic so don't take anything I have typed out as being a true statement . Its just how I see it and have learned from reading other posts on this site .

Won't disagree with anything you've noted but will say they're working well and they seem to match other reputable brands on the market so hopefully many years of service ahead.
