Brake Lines
1/4" Copper-Nickel Brake Line
Rust-proof lines that bend by hand and outlast the vehicle.
1/4" brake line shows up on longer rear runs, heavier trucks, and some fuel and transmission-cooler circuits. In copper-nickel you get a line that never rusts, bends by hand, and flares cleanly -- the last one you'll install.
