Torque settings brake lines

Thnaks-
The existing factory lines were tough to get off- my Z is a year old and do not use in winter but probably still get a little salt so had some corosion- used a ton of WD40 and a lot of patience eventually got fittings un-done without damage

Using a brake line wrench helps (also called a C-wrench). It connects more surfaces and is less likely to slip. I bought a combo 10/12mm at the parts store for short money.

Some Gorilla assembled those, like most every other fitting/bolt/nut on the car.

Torque specs? We don't need no stinkin torque specs (at least at the factory it seems)...

Factories typically over-torque the OE line fittings. GM is the worst offender, but others do it as well. They find it reduces leaks on the showroom floor, even though they readily acknowledge the are damaging threads and flares in the fittings. It's just something we get to live with. Corrosion just makes it worse.

When we did the stainless lines on Zpirates car we ran into this issue, with a damaged short rear caliper hardline upon dis assembly. It was an $8 part, but had to be ordered, leaving John's car stuck on my lift for almost a week...
