Detailed Description

Wagner Brake Z1051 is a rear parking brake shoe engineered for vehicles that rely on drum-style parking brake operation. The shoe’s OE-matched friction material helps maintain predictable engagement, while the precision-ground surface supports more uniform contact across the drum. This combination is important for drivers who want stable parking brake hold and consistent service-brake feel during rear brake maintenance.

The Z1051 part number is also useful when cross-checking brake shoe specifications during replacement planning.

This part cross-references 23135902 for the same application.

What This Part Helps Address

• Weak or uneven parking brake hold at the rear wheels
• Reduced drum contact from worn or glazed shoe material
• Noise or inconsistency during parking brake engagement
• Brake service needs on vehicles with rear drum-style parking brake shoes
• Fitment matching for rear brake maintenance on Silverado 1500, Sierra 1500, Tahoe, Yukon, and Escalade models

Installation Notes and Tips

Verify brake drum diameter, shoe width, and FMSI references before installation. The Z1051 is a rear parking brake shoe, so confirm the vehicle uses the listed rear application and compare the existing shoe profile to the 1701-S1051 or 1710-S1051 references. Inspect the drum surface for wear, scoring, or heat damage before installing new shoes, and replace or service the drum as needed to restore proper contact.

For best results, clean the backing plate contact points and confirm the parking brake mechanism moves freely before final adjustment. Always follow the vehicle service procedure for rear parking brake adjustment after installation.

Quality Assurance
