Brake Tube Help!

[FJ60BigLou]

Bleeding brakes in my Oct 85 FJ60 and found a small leak where the circled hard line attaches to the load sensor (I think that is what it is called??). The leak is coming from where the tube inserts into flange that screws down into the load sensor - not the threaded area but where the tube slips into the nut.

I thought there was a small rubber ring at the end of the tube - if so it is not there now. Also, if I need one, where can I find it.

SOR has used tubes for $33 but shipping is about $80. Anyone know where I can find a new or good used replacement tube?

While I really enjoy working in my 60 I am a new guy to all if this. Any help or advice is appreciated.

@Rainman are you making this part still?

The hard brake lines have a double flare, the seal is metal to metal, no O-ring.
Your nearest brake shop should be able to cut the line back and re-do the flare, should be plenty of line to work with because of the coiled section at the load proportioning valve. I guess there is a stress crack at the flare nut which is leaking, or the line has corroded through, unless the flare nut came loose...

He's right. No o-ring on any junction of brake lines. I don't have the patterns yet but could make a new one.

Also, since it's right below the expansion coil, you should be able to have the line's flare moved and re-flare it. It only uses 1/8" to create a flare. So 1/4" loss is nothing a coil can't expand to cover. Easy fix.

I just made a bunch of custom brake lines for my 62, and I used a bubble flare rather than double flare. 99% sure that Toyota uses DIN/ISO bubble flare on Land Cruisers. Someone please correct me if I'm wrong.

It's not that difficult to make your own hard brake lines. You just need a flaring tool and bender, along with the correct fittings.

Pretty sure you are wrong. At least, I've never seen a bubble flare on any Land Cruiser ever. It's always a double invert flare. But if you tighten down a bubble flare and you're lucky, it will invert and become an invert flare.

Agree, easy to make your own. I've had trouble reflaring stock tube-the metal is too hard, but the steel tube you buy in coils is easy to form and flare. The newer Copper Nickel tubing is even easier to work and rust free forever. Finding the proper flare nuts is more difficult, but even those are available several places.
