Front Brake Line - Toyota 4Runner Forum

I am replacing my front rubber hoses with SS braided hose, but the passenger side hardline won't thread back into the new hose. It came out fine from the old one

Is the non threaded part of the "nut" supposed to be this long or should it be all threaded?

Does the old rubber one thread back in? I assume the passenger side one threaded in fine?

That male fitting on the hard line should be threaded all the way down. If you take a look at your old rubber line, you're probably going to see remnants of those missing threads inside the female fitting.

Looks like you'll need to buy a new hard line or snag one off a wrecked 3rd Gen at a wrecking yard.

Couldn't I just bend a new one?

The old rubber hose will not thread back on

Yes I skipped to the passenger and finished that before realizing that my drivers hardline might be toast!

I can't get it to thread on the old hose anymore either...

Searched some more and I will pick up a 3/16" x 8" japanese brake line and bend it to shape.
All the work I do on this car takes 10x as long as it should. I had to cut the rear rubber line and use a 17mm socket to brake it free from the top of the diff, and then this line is somehow buggered up.

But you know it'll be done right, right? I try to keep that in mind when I get stuck on these week long "DIY" projects, lol

Get a new one from Toyota. They're super cheap, like $6

Like others have said, you need to replace it, but if you "have" to drive it while you source the replacement, you can grind the shoulder off threaded fitting (where the threads used to be) down a bit and take the hose out of the frame clamp and start it by hand. Use thread sealer or pipe tape and your old hose for now and throw it all out when you get the replacement hard line.

Toyota parts in Canada are $$$. They quoted me $16.50 before tax and it would be 2 weeks coming from the US.

I bought an 8" section of straight tube for $3.50 - I will try this tonight. I used a soft measuring tape and the OEM piece is ~10" so I will hopefully do less of a bend and make it work. I also bought an extra 8" and 12" if I screw up....

The fittings on the new tube are blue...maybe they will give me more HP

How do you bend metal brake line without crimping the line if you need to do some major bending? I reckon there must be some type of special tool to accomplish this. Hopefully the amount of bending you need to do is minimal and you won't have any issues with crimping the line.

I borrowed a tube bender... it's all part of the experiment. There is only 2 bends, not too complicated

Could you share a picture of what this tube bender looks like?

we used to do this all the time on old cars. there are several styles, one looks like a long spring and you put the pipe in it and make the gentle bends. they come in different diameters. but that stule you have to use before you install the "nut" and make the flare
the other looks like a half moon shape hard metal that you bend around it
