Keep rear braking smooth and quiet with the Wagner QuickStop ZX779 Semi-Metallic Disc Brake Pad Set. This rear-position pad set is an application-specific replacement with an OE fit-and-form design, dropping in for the 2004-2008 Chrysler Crossfire and a lineup of Mercedes-Benz models so worn rear pads can be swapped for fresh friction.
- Zero-copper friction: Built with Wagner's OE25 zero-copper, semi-metallic friction formulation.
- Even, consistent friction: A 100% post-cure process is designed to keep friction performance even throughout the life of the pad.
- Reduced noise: Application-specific design engineered to reduce noise-causing vibration.
- Included hardware: Ships with pad shims and abutment clips; premium stainless-steel hardware and OE-style lubricant are included in most applications. No wear sensor is included.
Wagner QS pads are designed and tested to help restore like-new braking performance for the listed applications. Country of origin: Mexico. Quantity per application: 1 set. For balanced braking, it is best practice to replace the pads on both wheels of the rear axle together as a matched set and to inspect the rotors, resurfacing or replacing them as the service procedure directs.
