Fitment Notes

• Rear axle only.
• Note the year gap: this kit covers 1996-2001 and 2004-2009 but not 2002-2003 - confirm your specific A4 generation and chassis code before ordering, as Audi's A4 changed platforms across this span (B5 generation through part of B6/B7).
• Exact hose length and fitting angle/style were not confirmed for this specific part number - Wilwood's Flexline Kits vary by application even within the same nameplate, so confirm exact configuration against Wilwood's own fitment listing before ordering.

Product Description

The Wilwood 221-17415 is a rear stainless steel braided brake flexline kit built specifically for the Audi A4, designed as a direct replacement for the factory rubber rear brake hoses across two separate production spans of this platform.

The braided stainless construction with a Teflon-lined interior resists the expansion that rubber hoses develop over time and under hard braking, delivering a firmer, more consistent brake pedal. Being DOT-approved, this kit is legal for street and highway use, not just track applications.

This kit covers the rear hoses only - A4 owners looking to replace both front and rear lines will need to pair this with Wilwood's corresponding front flexline kit for their specific generation. Given the year gap in coverage (1996-2001 and 2004-2009, but not 2002-2003), confirming your exact model year and chassis before ordering is the key fitment check here.
