Stock 510 Brake Hard Lines

[Stubby]

I cut through the hardline going to the rear brakes and I need to replace it. I have searched a little, but I can't seem to be able to nail down the diameter of the stock brake hardline. The smallest they sell at the autoparts store is a 3/16's.

 

If the line is a 3/16's line, will the fittings be the right thread pitch?

 

Thanks in advance.

The first KA swap I did, I cut through mine too, cutting out the trans tunnel, lol. I just took the whole thing out and went to the local hydraulic hose place, and had them match the ends and tube size. I just bought a new bulk straight piece and took it home and bent it up to match the original exactly. It was very easy. If you are worried about flaring the ends, just have them put them on for you at the place, then all you have to do is bend it. The whole thing cost me about $15.

OK, I will just I want to make sure I have the right size. Are you saying 3/16's is the right size or you don't know. I plan on bending the line myself and I don't have a problem flaring it.

I don't actually remember for sure, but I was thinking 1/4" myself. (I could be totally off though, it's been a long time.). That's why I just took the whole thing out first, so I had it with me when I went in to match up the tube size, length and thread pitch of the ends.

We smashed my brothers 510 by lifting trans to high installing engine ..and we took some ends off another Datsun ( which was 620 ) and he took those in .And did basically the same thing as creepy did..

 

 

But being able to cut tube just back from nut makes it easier to use 6 point wrench and not mess it up..

I use a pair of these to break the fittings loose, then just an open end wrench the rest of the way. I've been doing it this way for many many years now, and it doesn't damage the ends at all, no matter how stuck on there they are. A huge life saver, let me tell you.

Flare nut wrenches are one of the few things i only use Snap -on..on but not all nuts respect the fact they are the best..

 

. Where could a guy get a quality pair of those ?? Welding store?

That's vice-grip brand, "locking wrench".

 

I use regular vice-grips, works every time. Occasionally messes up the hex if they are really tight, but you can use vice-grips to retighten.

Yep, it's an Irwin vise grip "locking wrench".

 

Many hardware stores and tool stores carry them. I just saw some at my local Ace Hardware today. they come in 3 different sizes. I use the small and med.

 

The great thing about them is, they never damage the ends, but they always break them loose.
