Description
Experience enhanced braking response and long-term reliability with the USP Motorsports Stainless Steel Rear Brake Lines, specifically designed for the B5 Audi A4 and S4 Quattro models. These high-performance lines are a direct replacement for your factory rubber lines, offering a substantial upgrade in pedal feel, braking consistency, and overall safety—especially during aggressive driving or high-speed conditions.
Factory rubber brake hoses are prone to expansion under pressure, especially when your braking system experiences loads over 1,000 psi. This can cause a delayed or “spongy” brake feel, which reduces control and responsiveness. USP’s stainless steel braided lines are engineered to eliminate that expansion, maintaining constant hydraulic pressure for confident, precise braking.
Constructed with a stainless-steel woven exterior and DOT-compliant internal components, these lines are built for performance and safety. Each set includes four rear brake lines and all necessary installation hardware (if applicable), and can be installed in just a few hours using standard tools.
