Otherwise known as brake discs, your BMW 540 brake rotors are a vital component of your car's disc braking system. Your 540 brake rotors are metal discs located at each of the wheels in your all-wheel brake system. The function of your BMW 540 brake rotors is to work with your brake pads to generate the friction your car needs to come to a safe and controlled stop.

When you depress your brake pedal, the force moves through the hydraulic brake fluid and causes your calipers to move inward, which brings your brake pads into contact with your 540 brake rotors. The metal edges of the BMW 540 brake rotors grind against the lining of your brake pads and stop the rotational motion of your wheels. The life of your 540 brake rotors is often dependant on your brake pads.

If your car has metallic brake pads installed, your BMW 540 brake rotors will become worn much faster than with the non-metallic or "soft" variety. Also, if you do not change your brake pads, whether they are metallic or organic, after the thickness has worn down below a quarter of an inch, you risk damaging your 540 brake rotors. You can often tell when your BMW 540 brake rotors are damaged if your brakes start to make grinding noises or pull to one side.
