Like many things in life, this build often feels like two steps forward, one step backwards.. The last step to getting the wheels on was putting the steering links together. I painted my gearbox and new 555 rod ends and started pulling the hardware together only to find out that I apparently lost my TRE clamps. GREATTTTT. Now, gotta order those and wait on them. But, apparently there's only one TRE end clamp in the US, so I gotta wait on one from Japan.
Ok whatever, still tons of work to do. Just kind of annoying.. I like to see milestones completed.
In the meantime I switch to brake lines.. I want to get all this stuff done before the body goes on as I'd way rather do this kind of work standing up than laying on my back under a truck. I was going to reuse my existing lines as the lines themselves are actually in great shape.. No real rust on any of the lines themselves, but the nuts on the ends did have some surface rust (and I rounded over one or two getting them off).
I figured with the level of work going into everything else, it makes sense to just replace these now. After all, every other part of the braking system (except the pedal itself) will be new. So far I've ordered a new master, reman calipers, new pads, shoes, rotors, etc.
So I ordered some Nicopp line and M10 x 1 inverted flare fittings from AGS. I also got the fancy "fool proof" flaring tool from Eastwood because I've never made brake lines before, I'm redoing EVERY line on the truck, and I didn't want to have to worry about my flares not coming out correctly.
And, I of course still had issues. I ran a bunch of tests and my flares all came out a little weird. The hole in the middle was ovular and the sides looked kind of crimped:
After a bunch of testing and troubleshooting I came to the conclusion that this Nicopp line from AGS is just too soft.. The first stage in making an inverted flare is to essentially make a bubble flare. The second stage then presses that bubble flare into itself to make the cone of the inverted flare. So, it's important to make a good bubble flare to begin with.
I found that during that first step, instead of 'bubbling' out properly, the flare was kind of collapsing on itself, I think due to the line being too soft. Here you can see where the bubble has collapsed and the face become ovular:
Then, the second step seems to just crush all that together and the line being so soft, the tool effectively remolds it into the flare you see above.
It's definitely kind of frustrating as I specifically went out of my way to find good brake line and thought "Nicopp" name brand line (which i bought directly from the MFG) would be the best... But a deeper dive in google says others have also had issues with this line being too soft. So, maybe try a different brand.
In the end, I fixed the problem by performing the first step of making the bubble flare in two stages. I'd insert the line halfway to where it needed to be, start the bubble, and then insert it the rest of the way. This left a good bubble and ended up with a good flare (I think). Hopefully they don't all leak and I have to redo everything.
Other than the flares, working with the Nicopp line was great.. It bends super easily. I never even had to use any kind of a tool, just my hands. I got good tight clean bends each time.
