FAQ
Does this kit include everything needed to plumb my brake system?
This kit includes the essential AN fittings, adapters, flex lines, unions, tees, tube nuts, tube sleeves, and mounting clamps. You'll still need hard brake line tubing, brake fluid, caliper fittings (if required), and any vehicle-specific components.
Will this fit any GM master cylinder?
It is designed for GM master cylinders that use 9/16"-18 and 1/2"-20 inverted flare outlet ports. Always verify your master cylinder port sizes before ordering.
Why are -3 AN brake lines commonly used?
-3 AN stainless braided brake lines provide excellent hydraulic performance with minimal line expansion, resulting in a firmer brake pedal and improved durability compared to conventional rubber brake hoses.
Is this kit intended for production vehicles?
No. This kit is designed primarily for custom-built off-road vehicles, race buggies, rock crawlers, and fabricated chassis where custom brake plumbing is required.
Why choose a complete plumbing kit instead of buying fittings individually?
A pre-configured kit eliminates compatibility issues, reduces ordering mistakes, and provides matching components that simplify installation while creating a cleaner, more serviceable brake system.
