Wagner Brake MX909 Disc Brake Pad Set - Rear

Wagner ThermoQuiet MX909 Rear Brake Pads

Wagner Brake ThermoQuiet MX909 disc brake pads are built for rear brake service on select Chevrolet Silverado 3500 and GMC Sierra 3500 applications. This rear disc brake pad set uses a semi-metallic friction formula with slotted faces, chamfered edges, and an integrally molded insulator for quieter braking performance.

Key Features

• Zero-copper friction formulation
• Integrally Molded Insulator (IMI) technology for reduced brake noise
• Semi-metallic friction material for OE-style braking feel
• Slotted design and chamfered edges
• Pad shims included
• Abutment clips included
• Mechanical pad wear sensor included
• Outer and inner pad friction material thickness: 0.744

ThermoQuiet Brake Pad Line

The Wagner ThermoQuiet line focuses on quieter operation through pad construction and insulator technology rather than relying on aggressive friction characteristics alone. For drivers servicing rear brakes on a Chevrolet Silverado 3500, Silverado 3500 HD, Silverado 3500 Classic, GMC Sierra 3500, Sierra 3500 HD, or Sierra 3500 Classic, the MX909 is a direct-fit option built around OE-style semi-metallic material and noise-control features.

Detailed Description

The Wagner Brake MX909 is a rear disc brake pad set engineered for select 2001-2010 Chevrolet Silverado 3500 and GMC Sierra 3500 trucks. It uses a semi-metallic friction composition with a slotted surface, chamfered edges, and pad shims to support consistent pedal response and controlled wear. The included mechanical wear sensor adds a direct wear indication for the rear brake service interval. This part cross-references Centric Parts (e.g., 104.09090, 106.09090) for the same application.

Common Brake Issues Addressed

• Rear brake squeal during stops
• Uneven pad wear on heavy-duty truck rear brakes
• Reduced braking consistency from worn friction material
• Brake wear indicator service replacement needs
• Noise and vibration from aging rear pad hardware interfaces
