What makes stainless steel braided brake lines better than rubber ones?

Stainless steel braided lines are more resistant to expansion under pressure compared to rubber hoses. This means you'll get a firmer, more consistent brake pedal feel, especially during hard braking.

Does this kit include all the necessary brake lines for my 4WD vehicle?

Yes, this kit includes three lines, which are the main brake hose assemblies needed for your 1979-1986 GM 4WD truck or SUV.

Are the fittings included in this kit corrosion-resistant?

The kit features zinc-plated fittings, which are designed to resist corrosion and maintain a solid connection over time.

About this part

Product Details

Russell is known for making reliable performance plumbing components, and this brake line kit for your 1979-1986 GM 4WD truck or SUV is a great example. If you're working on your K10, K20, Blazer, Jimmy, or Suburban and want to upgrade your braking system, these lines are a solid choice. They replace your factory rubber hoses with a more robust setup that can make a noticeable difference in pedal feel, especially if your old lines are getting spongy.

This kit comes pre-assembled with stainless steel braided hose, which is a step up from standard rubber. The braiding helps prevent the hose from expanding under pressure, giving you a firmer and more consistent pedal. Plus, the zinc-plated fittings are corrosion-resistant and designed to fit right into your factory mounting points, making installation straightforward. These lines meet DOT guidelines and are legal for street use in all 50 states, so you can be confident they meet safety standards.

This kit includes three lines, covering the main brake circuits for your 4WD vehicle. It's a good idea to check your existing lines for any signs of wear or damage, and if they're looking old, replacing them with a quality kit like this can improve your vehicle's overall braking performance and safety.
