Description

Reliable Stopping Power: Left Hand Rear Drum Brake Lever

Restore your braking confidence with this OEM-Replacement Left Rear Brake Lever. Specifically designed for scooters utilizing the 50cc/80cc 139QMB engine platform with a cable-actuated rear drum brake, this lever offers a factory-perfect fit and feel. Finished in a durable matte black coating, it provides the ergonomic leverage needed for smooth, consistent deceleration in urban riding conditions.

Technical Performance Features

  • Direct OEM Replacement: Matches factory specifications for the Chicago Scooter Company lineup and dozens of other QMB139-based bikes.
  • Cable-Actuated Design: Engineered with the correct pivot geometry for drum brake cables, ensuring a "snap-back" feel without binding.
  • Durable Alloy Construction: High-strength cast aluminum body resists bending and snapping during tip-overs or heavy emergency braking.
  • Weather-Resistant Finish: The semi-gloss black powder coat protects against corrosion and UV fading.

Mechanic's Note: If your brake lever feels "mushy" even with a new lever, check your rear brake cable for stretching or fraying. For a balanced look and feel, we recommend replacing the Right-Hand Disc Brake Lever (0800-4038) at the same time if your current set is faded or mismatched.
