What type of flare do we have on stock brake lines?

A brake line blew out yesterday, so needs to be replaced. Stock steel line under the hood, a long one (between what i think is the abs unit and a fitting down on the frame rail beneath the master cylinder area), majority of the line looks good except for the one corrosion spot that blew out.

I have copper-nickle brake line material and bending and flaring tools (for double flares). Hoping I can make a new one myself.

Then I get to pressure bleed the front brakes all over again. Just when I thought I had achieved good/decent brakes on the truck, after doing the front big brake upgrade last year. Oh well, atleast it happened within a few miles of home and not on a towing road trip.

 

Standard inverted flare, 3/16th" line with metric fittings. M10, I think.

I think the only ones who use the bubble flare fittings are older European cars

 

Standard SAE “double flare” ?

 

Yep, nothing fancy. Can get the tube and couplings at AutoZone.

You will need a double flaring tool.

This is the tool I used on my '98.

It's fairly idiot proof...unless you forget to install the fitting on the tube 1st...

I may know a guy who forgot...Titan Tools 51535 3/16-Inch...

Yeah, i’ve got the tools for double flare, just never had to replace a line on my 2006 DC. Replaced all the lines on a Ford this past summer and only missed putting the flare nut on one time. Hopefully the bleeding goes smooth as after the line blew l had to nurse it home and pumped all of the fluid out of the front circuit.

 

Would it make sense to use the fittings from the original? (assuming they are in decent shape)

 

Sure does. If they look good, they are fine to reuse.
