Product Description:
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.

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
