Russell Performance R08406S Cycleflex Stainless Brake Line Two-Line Race Kit

The Russell Performance R08406S Cycleflex Two-Line Race Kit is a performance-engineered stainless steel braided brake hose kit designed to deliver consistent, firm braking feel at the track or on the street. Built around a PTFE inner liner supported by a stainless steel outer braid, this kit virtually eliminates brake hose expansion under pressure — the primary cause of a spongy or inconsistent brake lever.

This kit uses a special two-line configuration that routes both hoses directly to the master cylinder via a double-length banjo bolt (supplied as necessary). The longer hose connects to the left caliper and the shorter hose connects to the right caliper, replacing the stock three-hose setup and brake junction entirely. The result is a cleaner, simpler brake circuit that is easier to bleed and service — especially valuable during track day maintenance.

Key Features:

• PTFE inner liner with stainless steel outer braid eliminates brake line expansion
• Two-line direct-to-master-cylinder configuration replaces OEM three-hose setup
• Longer hose connects to left caliper; shorter hose connects to right caliper
• Extruded clear coat over stainless braid for abrasion protection on painted surfaces
• Double-length banjo bolt included as necessary for proper master cylinder fitment
• Meets all D.O.T. guidelines
• All necessary hardware included

Whether you're pushing hard on a closed course or upgrading your street bike's braking system, the Russell Cycleflex Two-Line Race Kit provides the firm, repeatable lever feel serious riders demand.
