Wagner Brake Z446R Drum Brake Shoe - Rear

Wagner Z446R Rear Drum Brake Shoe

The Wagner Z446R is a rear drum brake shoe built for vehicles using 11 x 2-1/2 inch drum brakes with a riveted shoe design. It uses OE-matched organic friction material and precision-ground surfaces to improve friction-to-drum contact for consistent braking response.

Compatible With rear brake applications on Dodge B1500, B2500, Ram 1500 Van, Ram 2500 Van, Chrysler Town & Country, and other listed Chrysler, Dodge, and Plymouth models. The Wagner brake shoe line focuses on OE-style friction characteristics and accurate fitment for drum brake service.

Detailed Description

Wagner Z446R brake shoes are engineered for rear drum brake systems that require an 11 inch x 2-1/2 inch riveted shoe configuration. The organic friction compound is selected to match OE-style braking behavior, while the precision-ground construction helps maximize contact across the drum surface. This supports stable pedal feel and predictable rear brake performance in everyday driving and service replacement applications.

This part cross-references Bendix Premium Brake Shoes 446 for the same application. Use Z446R when servicing rear drum brake systems on vehicles such as the Dodge B1500, Dodge Caravan, and Chrysler Town & Country where the listed drum size and riveted shoe design are specified.

What It Helps Address

• Rear brake noise caused by worn or uneven drum shoes
• Reduced braking performance from thin or heat-aged friction material
• Poor drum contact from worn shoe surfaces
• Brake pulsation or inconsistent rear brake engagement
• Service replacement needs on riveted drum brake systems

Installation Notes and Tips

• Verify drum diameter, shoe width, and riveted shoe configuration before installation.
• Inspect the brake drum for scoring, taper, or out-of-round wear before reassembly.
• Replace or service related drum brake components as needed during brake work.
• Confirm fitment for the exact year, make, model, and rear brake setup listed for the vehicle.

Quality Assurance

Wagner brake shoes are built with OE-matched friction materials and precision-ground surfaces to support consistent drum-to-shoe contact. The Z446R is identified by FMSI S446R and is manufactured for the specified rear drum brake applications listed in the fitment data.
