Detailed Description

The Wagner Z972 parking brake shoe is engineered for rear drum-style parking brake service on 2008-2015 Cadillac CTS and 2010-2014 Chevrolet Camaro applications listed in the fitment data. Its OE-matched friction material helps maintain predictable engagement, while the precision-ground surface supports full contact with the brake drum for consistent operation. This part number, Z972, is a focused replacement for rear parking brake shoe maintenance where correct lining size and drum diameter matter.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Weak or inconsistent parking brake hold
• Noise from worn rear parking brake shoes
• Reduced friction from glazed or thin lining material
• Poor drum contact caused by worn shoe surfaces
• Service replacement for rear parking brake shoe wear on Cadillac CTS and Chevrolet Camaro models

Installation Notes and Tips

• Verify rear fitment against the vehicle year and model before installation.
• Inspect the brake drum surface for scoring, heat spots, or out-of-round wear before reassembly.
• Confirm the shoe width and drum diameter match the existing parking brake hardware.
• Clean the backing plate and contact points so the shoe seats evenly.
• After installation, test parking brake engagement and release before returning the vehicle to service.

Quality Assurance

Wagner Brake uses OE-matched friction materials and precision-ground manufacturing methods to support consistent brake performance and drum contact. The Z972 is built to the listed FMSI dimensions for accurate rear parking brake shoe service.
