3/16″ & 1/4″ Copper Coated Steel Brake Line Kits
The 4LifetimeLines Copper-Coated Steel Brake Line Kit includes both 3/16″ and 1/4″ copper-coated steel tubing designed for reliable brake line replacement with enhanced corrosion protection over bare steel. Each tube features a protective copper coating that helps guard the steel core from rust, road salt, and moisture—while maintaining strength and bendability for professional brake plumbing work.
Both tubing sizes bend and route smoothly without kinking and work with standard flaring tools, allowing technicians and experienced DIYers to create secure, leak-resistant single and double flares. This kit provides shop-ready material for custom routing, routine maintenance, and full brake system replacement, giving installers dependable performance and easier installs. Backed by the 4LifetimeLines lifetime warranty, it delivers lasting corrosion protection and confidence on every job.
