brake lines: mix US and metric?
 

Our '99 Cavalier had a rotten rear brake line. So, I cut it back to
good metal, flared the end, and replaced the pipe with some 3/16" stuff
I had. I got to the axle end, and it suddenly occurred to me that it's
probably METRIC. And, on closer inspection, it appears to need a 'DIN
flare' to mate with the axle hose. So, ...

It looks like I can just use one section of 'metric' tubing, to mate
with the axle hose, and cut the other end off, and put a regular (SAE)
flare there, to mate with the 3/16" tubing I've installed.

Yes?

Thanks,
G

Most of the flares you will find will be SAE.
Most domestic made vehicles will have SAE threads.

When you find Metric threads you will usually also find bubble flares
instead of the standard double flare.

These items go out the window on a few models where a domestic maker
sourced the vehicle from a foreign company.

Yes, but I'd hardly be eager to pinch pennies on essential safety items.
How much of a bitch is it to replace it end-to-end?

It turns out, they have an SAE to metric adapter, for $1.70. Better
than I'd hoped. Thanks to all.
