Product Details

Cardone Unloaded Caliper 19-3121NM is remanufactured to OE specifications and pressure-tested before release. The caliper body is restored with new high-temperature EPDM rubber seals, durable piston components, and new stainless steel hardware clips and mounting pins where applicable. This approach supports reliable braking response while reducing the raw material and energy demand associated with manufacturing a new part.

This part cross-references Audi OE numbers 4E0615403 and 4E0615404 for the same application. Use Cardone 19-3121NM when replacing a rear left disc brake caliper on an Audi A8 Quattro from 2004 through 2007.

• Sticking or seized caliper piston movement
• Corrosion-related caliper wear on the rear left corner
• Soft or inconsistent brake pedal feel caused by caliper-related faults
