xHeart,

Congrats...

The most difficult is always making a correct bubble flare in situ.
As I mentioned above re my 2006 BMW X5, it was challenging to make the bubble flare in situ.

How was the Neiko bubble flare tool?

How was the Neiko bubble flare tool?

Indeed, in situ is ten fold harder. Except for the struts, everything else was removed to make it a workspace -- used glove with grip and dexterity support. Volvo wheel well is huge, you can move in if you're fit.

The choice was between OTC and NEIKO.

I found Volvo's copper brake line wall a bit thicker, real hard to handle and shape barehand, compared to the steel sample I picked up for practice from the neighborhood auto parts store.

NEIKO kit needed lubrication as first step, one butterfly nut's matting surface was uneven and needed flattened.

The yoke to fasten 4.75mm tube gripped the thicker wall real firm. Found the adapter sticking a little afterward, even with careful prep and lubrication.

Two things...
First, the flared-base that sits on the M10x1 nut does not need to be flared-flat to max at the freshly flared line, the flatness is reached during the life-cycle, with each repair providing good seal. Second, a good leak proof connection begins with flared line dripping, and ends with final turn of the nut making a good seal and stopping the drip completely -- live as it happens.

As my friend says, "THAT'S ALL BOYS..."

Haha,

This is exactly what I learn from "garagejournal" forum...

These "garagejournal" forum folks taught me when making bubble (or double) flare:

- Stop when the die is about one business card thickness from the yoke, or about 1mm.
So the bubble flare is kind of 98% done. The final torque from the bolt in the car will seat it.

- When installing it, tighten the bolt a bit but leave some room for further tightening. Mine leaked a drop here and there. After further tightening, it is bone-dry.

- And yes, I applied a tiny bit of anti-seize on the bolt threads.
