Blue Print Vented Brake Disc (ADBP430076) Fits: BMW Rear Axle

Along with brake pads and callipers, brake discs are a crucial component of your vehicle's braking system. When force is applied to the brake pedal, brake fluid creates pressure and squeezes the brake pad against the rotor, creating friction that slows and stops the motion of the vehicle. This action produces a lot of heat that must then be dispersed.

The amount of heat generated depends on numerous factors, such as the speed and weight of the vehicle, as well as the force applied to the brakes while travelling at high speeds. This waste heat created by friction can cause your brakes to become less effective, fading in quality over time due to prolonged or heavy braking.

This means that overheated discs can suffer from excessive wear, cracking, and Disc Thickness Variation (DTV), which in turn requires the driver to press even harder when braking to slow or stop the vehicle.

For this reason, it is important for driver safety that the vehicle's brake discs are constructed with durable materials and to precise measurements so that the brake discs perform optimally, and efficiently disperse the heat generated when braking or slowing down. This is why your brake discs must consist of the correct weight, mass, and thickness, and be designed with high-quality materials that include high carbon composition.

All Blue Print components are developed and manufactured to meet OE specifications to be direct replacements, as well as undergoing rigorous testing and quality checks to keep products to a high standard.
