Wagner Brake Z908 Parking Brake Shoe - Rear

Wagner Z908 Parking Brake Shoe for Rear Fitment

The Wagner Z908 parking brake shoe is built for rear brake drum applications that require OE-matched friction and consistent drum contact. It is a direct-fit option for 2006-2010 Hummer H3 rear and 2009-2010 Hummer H3T rear applications.

Key Features

• OE-matched friction material for steady parking brake performance
• Precision-ground surfaces to improve friction-to-drum contact
• Brake drum diameter: 8.200 inches
• Brake shoe width: 0.980 inches
• Primary friction material thickness: 0.180 inches
• FMSI number 1615-S908 for identification and catalog matching
• Wagner Z908 parking brake shoe for rear drum brake service

Product Details

Wagner Brake uses friction materials selected to match OE-style performance requirements, helping the parking brake shoe maintain consistent engagement against the drum. The precision-ground construction supports even contact across the braking surface, which is important in rear parking brake systems where drum fit and lining geometry affect holding performance. This Wagner Z908 part is identified by FMSI lining 1615 and FMSI steel S908, and it cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 2006-2010 Hummer H3, rear and 2009-2010 Hummer H3T, rear. The Wagner Z908 is a focused replacement for rear parking brake service on these vehicles, and the fitment data confirms use on Hummer H3 and Hummer H3T rear positions only.

Common Issues This Part Can Address

• Weak parking brake holding force at the rear wheels
• Uneven shoe-to-drum contact
• Noise or vibration from worn parking brake shoes
• Reduced braking consistency in drum-style parking brake systems
• Wear-related loss of friction material thickness

Installation Notes and Tips

Verify drum diameter, shoe width, and FMSI match before installation. Inspect the brake drum surface for scoring, taper, or excessive wear, since drum condition affects shoe contact and parking brake performance. Confirm rear-position application on the Hummer H3 or Hummer H3T before service, and compare the removed shoe to the Wagner Z908 for shape and lining profile.

Quality Assurance

Wagner Brake positions this shoe line around OE-matched friction materials and precision-ground manufacturing for consistent brake performance and drum contact. The Z908 is cataloged with defined FMSI and dimensional specifications to support accurate parts selection for rear parking brake service.
