Detailed Description

The Wagner Brake SevereDuty SX2405 is a rear disc brake pad set for Chevrolet Express 3500, Chevrolet Express 4500, GMC Savana 3500, and GMC Savana 4500 applications. The semi-metallic compound, slotted face, and mechanical wear sensor make it a practical choice for commercial van brake maintenance where repeat stopping and load demands matter.

This part cross-references Dynamic Friction Company (e.g., 1214-2405-00, 1214-2405-01) for the same application.

What It Helps Address

• Brake pad wear that requires rear pad replacement.
• Noise or vibration related to worn pad surfaces.
• Heat buildup during frequent stop-and-go driving.
• Uneven braking feel from aging rear pads.
• Service intervals that call for wear sensor replacement.

Installation Notes

Verify rear fitment by year, make, and model before installation. Inspect caliper condition, rotor surface, and pad contact points during service. Replace worn hardware and confirm the wear sensor is routed correctly before returning the vehicle to service.
