Brake Spring WG9100440061 Sinotruk 

Product Introduction

This Brake Spring WG9100440061 is an OEM heavy-duty dual-coil brake return spring, specifically engineered for the drum brake systems of Sinotruk heavy-duty trucks and commercial vehicles. Precision-formed from premium spring steel with a symmetrical dual-coil design, it delivers consistent, balanced tension to ensure reliable brake shoe retraction under the extreme mechanical stress of heavy-load transportation and frequent braking cycles.

Performance

• Symmetrical Dual-Coil Design: The matched double-coil structure provides uniform tension distribution, eliminating uneven brake shoe retraction and preventing premature wear of brake components.

• High-Performance Spring Steel: Crafted from heat-treated chrome-vanadium spring steel, it exhibits exceptional fatigue resistance and tensile strength, resisting permanent deformation over millions of brake applications.

• Corrosion-Resistant Black Oxide Finish: The industrial-grade black oxide coating forms a durable barrier against rust, road salt, and debris, ensuring long service life in harsh undercarriage environments.

• Precision Hook Forming: Computer-controlled hook forming ensures exact dimensional accuracy, guaranteeing a secure fit with brake shoe retaining holes and preventing disengagement during operation.

Core Function

1. Delivers balanced, consistent tension to retract both sides of the brake shoe assembly simultaneously after braking, eliminating brake drag and reducing unnecessary wear on linings and drums.

2. Maintains precise brake shoe-to-drum clearance, ensuring responsive pedal feel and consistent braking performance across all operating conditions.

3. Withstands repeated cyclic loading and extreme temperature fluctuations without losing tension, serving as a critical safety component of heavy duty truck brake parts.
