If you have a disc braking system installed on your car—and you probably do—then you have a set of BMW 540i brake rotors. Your 540i brake rotors are metal discs that work with your brake pads to generate the friction your car uses to stop. Of course, your brakes are perhaps the most important system of your car, so it is important that you make sure they are in good working order.

This includes taking good care of your BMW 540i brake rotors. One of the best ways to ensure a long life for your 540i brake rotors is to make sure your car is equipped with organic or "soft" brake pads.

Since the braking action of your car is created through the contact between the brake pads and the BMW 540i brake rotors, it stands to reason that one of those parts is going to erode. If your car uses metallic brake pads, made with powdered copper or bronze and some fillers, your 540i brake rotors will wear down faster than your pads and need to be replaced more often.

However, if you use organic brake pads, there is not nearly as much wear to your BMW 540i brake rotors. This means that as long as you change your brake pads when necessary, your 540i brake rotors should last for quite a while. Be aware, however, that if you let your brake pad lining thickness drop below an eighth of an inch, you will be damaging your BMW 540i brake rotors when they begin scraping against the metal backing plate instead of the frictional lining surface. If you prefer the feel or the additional stopping power of metallic brake pads, make sure you replace your 540i brake rotors as soon as they become worn.You can order a set of high-quality BMW 540i brake rotors from our extensive online catalogue.
