Hope it is not made of brass because in many areas brass tubing is not allow on brake line because it is to fragile.
In any event have a happy new year, and continued your good report.

I believe the picture shows copper tubing...
The new brake line are much better now than the old steel lines..More resistant to rust..
Brass tubing would never take the pressure for a long live brake line.
Here is the latest.\
The Move To Copper-Nickel Tubing
Copper had been proved since the early days to have many good attributes. It was easy to bend and had very high corrosion resistance, but there was concern about its low corrosion-fatigue strength. When copper-nickel was introduced, it displayed corrosion resistance similar to copper, higher general strength and better fatigue strength. Good formability allows ease of flaring and bending, and although the metal cost is greater than that of steel alternatives, copper-nickel is very attractive in view of its extra life, trouble-free installation and safety/reliability characteristics.
Properties of Copper-Nickel Brake Tubing
The copper-nickel alloy used for brake tubing typically contains 10% nickel, with iron and manganese additions of 1.4% and 0.8% respectively. The product conforms to ASTM B466 (American Society for Testing and Materials), which specifies dimensions, tensile strength and yield strength. Formability and internal cleanliness conform to specifications SAE J527, ASTM A254 and SMMT C5B (Society of Motor Manufacturers and Traders). Also, the alloy meets the requirements for pressure containment, fabrication and corrosion resistance for ISO 4038 (International Standards Organization) and SAE J1047.
