Russell Stainless Steel Brake Line Kit - 2006-2011 Honda Civic Si - 684470

Russell 684470 Stainless Steel Braided Brake Lines for 2006–2011 Honda Civic Si

Upgrade the factory rubber brake hoses on your 2006–2011 Honda Civic Si with the Russell 684470 stainless steel braided brake line kit.

This application-specific kit includes four brake hoses for the front and rear disc brake system. Russell stainless braided hoses are designed to reduce hose expansion under hydraulic pressure, which can provide a firmer and more consistent brake pedal feel compared with aging factory rubber hoses.

The lines are factory assembled and use zinc-plated fittings for corrosion resistance and easier direct-fit installation on compatible stock brake systems.

Vehicle Fitment

Russell’s application data lists the 2006–2011 Civic Si and specifically includes the 2008 Civic MUGEN Si.

This kit is intended for the Civic Si front-disc/rear-disc brake configuration.

Do not assume compatibility with Civic DX, LX, EX, Hybrid, or other trims based only on model year or chassis generation.

Vehicles modified with the following should have hose length, fitting style, mounting brackets, and caliper connections verified before ordering. :

• Aftermarket big brake kits
• Different front or rear calipers
• Brake conversions
• Modified knuckles or brackets
• Non-original brake hose routing

Why Upgrade to Stainless Steel Braided Brake Hoses?

Factory rubber brake hoses can flex and expand slightly as hydraulic pressure increases. That expansion can contribute to a softer pedal feel, particularly as the original hoses age.

The stainless outer braid used on Russell brake hoses reinforces the flexible hose and helps limit expansion under pressure. This can provide:

• Firmer pedal feel
• More consistent pedal travel
• Improved brake modulation
• More direct hydraulic response

The brake hoses themselves do not increase caliper clamping force or replace the need for properly functioning pads, rotors, calipers, fluid, and tires.

What’s Included

• 2 front stainless steel braided brake hoses
• 2 rear stainless steel braided brake hoses

Brake fluid, hard brake lines, calipers, brake pads, rotors, and installation tools are not included unless specifically shown or stated.

Installation Note

Professional installation is recommended.

Before installation:

• Compare each replacement hose with the original hose
• Inspect the factory hard lines and flare nuts for corrosion or damage
• Confirm each hose follows the original routing
• Do not twist the hose during installation
• Verify clearance from the wheels, tires, suspension, and exhaust
• Check hose clearance through the full steering and suspension range
• Use the proper flare-nut wrench when disconnecting the original brake lines

After installation, bleed the brake system using the brake fluid specified by Honda. Inspect every connection for leakage and confirm a firm brake pedal before driving.

Recheck hose routing and fittings after the initial road test.
