Detailed Description

Wagner Brake Z860A is a rear drum brake shoe set for vehicles using a 9.000-inch brake drum and 1.625-inch shoe width. The organic friction compound is selected for predictable braking behavior, while the precision-ground shoe surface helps promote even contact across the drum. This part is a strong match for rear brake service on 2004-2007 Chevrolet Malibu and 2005-2007 Saturn Ion applications that use the listed brake configuration. The Z860A also cross-references Monroe Shocks & Struts 172286 for the same application.

Wagner’s Wagner brake line focuses on OE-style friction performance and fit consistency, making the Z860A a practical choice when replacing worn rear drum brake shoes on Chevrolet Malibu and Saturn Ion models. Part number Z860A is also identified by FMSI S860A.

What It Helps Address

• Squealing or noisy rear drum brakes caused by worn friction material
• Reduced braking response from thin or glazed shoe linings
• Uneven drum contact that can affect pedal feel
• Poor parking brake engagement related to worn rear shoes
• Brake service needs on rear drum-equipped Chevrolet Malibu and Saturn Ion vehicles

Installation Notes and Tips

Verify drum diameter, shoe width, and rear brake configuration before installation. Inspect the brake drum for scoring, heat spots, or out-of-round wear, and replace or machine the drum as needed. Clean the backing plate contact points and confirm the parking brake levers transfer correctly during assembly. Because mounting hardware is not included, reuse or replace related service components as required during brake work.

Quality Assurance

Wagner Brake manufactures this shoe with OE-matched friction materials and precision-ground surfaces to support consistent brake performance and drum contact. Part number Z860A is built to the S860A FMSI specification for the listed rear applications.
