Detailed Description

Wagner Brake Z846 is a rear parking brake shoe engineered for vehicles that rely on a drum-style parking brake assembly. The OE-matched friction formulation supports predictable engagement, while the precision-ground construction helps the shoe seat evenly against the drum surface. This combination is important for maintaining parking brake performance on Lexus GS300, Lexus GS430, Lexus IS300, Lexus SC430, Toyota Sienna, and Toyota RAV4 rear applications.

The Wagner product line focuses on replacement brake components that follow original-equipment fit and material targets. For buyers searching for a rear parking brake shoe for 2002-2010 Lexus SC430, 2004-2010 Toyota Sienna, or other listed applications, Z846 provides a direct match by FMSI and vehicle fitment.

What It Helps Address

• Weak or inconsistent parking brake holding power
• Noise from worn rear parking brake shoes
• Poor drum-to-shoe contact from uneven wear
• Reduced parking brake engagement on rear drum assemblies
• Service replacement for worn OE-style parking brake shoes

Installation Notes and Tips

Confirm drum diameter, shoe width, and FMSI match before installation. Inspect the brake drum for scoring, heat spots, or out-of-round wear, since drum condition affects shoe contact and parking brake performance. Clean the backing plate and verify all contact points are in good condition before fitting the new shoes. After installation, adjust the parking brake according to the vehicle service procedure and verify proper hold on a safe incline.

Quality Assurance

Wagner Brake uses OE-matched friction materials and precision-ground components to support consistent fit and braking contact in the specified rear applications.
