Introduction to Truck Brake Shoes with HD (High-Density) Metallic Mixture
HD Metallic brake shoes mixture is a premium brake shoes friction material engineered for heavy-duty trucks requiring exceptional braking performance under extreme conditions. This brake shoes formula combines high-density metallic alloys (e.g., steel, copper-free composites) with advanced binders and modifiers, delivering superior durability and heat resistance. Below is a technical overview, advantages, and storage guidelines for this robust friction material.
Technical Parameters of HD metallic brake shoes mixes
