Detailed Description

PowerStop B1021L is a rear drum brake shoe set engineered for Hyundai Accent, Hyundai Elantra, Hyundai Venue, and Kia Rio applications that use drum-style rear braking. The bonded semi-metallic lining supports consistent friction characteristics, while the post-cured material helps reduce the initial bedding-in period. Precision cam grinding improves drum contact, and the chamfered design helps control brake noise during operation. This part cross-references Wagner Brake Z1021 for the same application.

Common Issues This Part Addresses

• Reduced rear braking performance
• Poor parking brake engagement
• Brake noise or chatter from worn drum shoes
• Uneven shoe-to-drum contact
• Rust-related wear on older brake shoe assemblies

Installation Notes and Tips

Verify rear drum brake fitment by year, make, and model before installation. Inspect the drum surface, wheel cylinders, return springs, and adjuster hardware for wear before reassembly. Because mounting hardware is not listed as included, reuse or replace related hardware as needed during service. After installation, follow the vehicle manufacturer’s brake adjustment and break-in procedure.

Quality Assurance

PowerStop builds its brake shoe line to meet strict OEM-style standards for fit and material consistency. B1021L uses asbestos-free, copper-free friction material and coated steel construction to support corrosion resistance in everyday service.
