Russell Stainless Steel Brake Lines for Acura RSX and Civic Si
Improve brake-pedal response and consistency with the Russell 684890 stainless steel braided brake line kit.
Designed as a direct-fit replacement for the original rubber brake hoses on compatible 2002–2006 Acura RSX and 2003–2005 Honda Civic Si models, this four-line kit services both the front and rear brakes. The stainless steel braided construction helps limit hose expansion under hydraulic pressure, providing a firmer pedal feel and more consistent brake response during everyday driving, spirited use, and track events.
Each line is factory assembled with zinc-plated fittings for added protection against corrosion. Russell brake line kits are manufactured to meet applicable U.S. Department of Transportation FMVSS 106 requirements.
