The principle of the brake disc is to clamp the brake disc through the brake caliper, so that it contacts the tire to generate friction, thereby slowing down or stopping the rotation of the wheel to achieve the braking effect. EAN Auto Parts presents high-performance rear brake discs (rotors) specifically engineered for multiple BMW X5/X6 generations including E70, F15, F85, E71, F16, and F86 models. EAN is an excellent brake disc manufacturer in China.These precision-crafted braking components deliver exceptional stopping power while meeting strict OEM specifications. Product Specifications OE Number: 34216793247 Diameter: 320MM Thickn , ess: 20MM (minimum wear limit: 18MM) Height: 78.5MM Bolt Pattern: 5 lug holes Weight: 8.12KG Material: HT250 gray cast iron with enhanced carbon content Braking System Operation The brake rotor (also called brake disc) works in conjunction with your vehicle's calipers and pads to create the friction needed for safe deceleration. Here's the step-by-step process: Driver applies pressure to brake pedal Hydraulic fluid transmits force through brake lines Calipers squeeze high-friction brake pads against rotating disc brakes Friction converts kinetic energy into thermal energy Vented rotor design dissipates heat efficiently Wheel rotation slows until desired speed or stop is achieved Engineering & Material Advantages Our BMW rear brake rotors feature: Premium Alloy Composition: HT250 standard cast iron with optimized graphite structure for consistent friction performance Thermal Management: Directional vanes between disc surfaces promote airflow, reducing brake fade during heavy use Surface Treatment: Zinc plating on non-friction surfaces provides corrosion resistance Precision Machining: Computer-balanced to ensure vibration-free operation up to 1,200 RPM
