Brake Line Kits

Brake Lines & Complete Replacement Brake Line Kits

Why Upgrade Your Brake Lines?

Your brake pedal is only as strong as the brake lines carrying hydraulic pressure to each wheel. Most factory steel tubing corrodes, kinks, or pin-holes after a few winters—especially if you drive in the Rust Belt or anywhere road salt is common. Upgrading to our rust-proof copper-nickel or stainless-steel brake line kits eliminates those weak spots and restores firm, predictable stopping power. Every coil, fitting, and adaptor we sell is DOT-approved and backed by a lifetime warranty, so you can focus on the road (or the trail) instead of worrying about hidden leaks.

Ready to Upgrade?

Scroll down to the product grid and grab the brake line kit that matches your build. Every kit ships fast, installs easy, and carries our unconditional lifetime warranty—so you can stop with confidence for a lifetime.
