BMW 525i brake rotors are the "disc" part of your disc braking system. Your 525i brake rotors are metal discs that spin with your wheels, keeping your brakes clean through centrifugal force by throwing off mud and water. The main function of your BMW 525i brake rotors, however, is to work with your brake pads to create the necessary friction to bring your car to a safe and controlled stop.

When you depress the brake pedal, the force is sent through hydraulic fluid to your brake calipers, which bring the brake pads on either side of your 525i brake rotors into contact with the disc. Friction is created between the brake pad lining and the BMW 525i brake rotors, stopping the rotational motion of your wheels.

Since they are moving parts, your 525i brake rotors are subject to wear and tear through normal use. However, you can extend the life of your BMW 525i brake rotors simply by maintaining your brake pads. There are two different types of brake pads, and each of them means something different to your 525i brake rotors. Metallic brake pads, such as those made with copper or bronze, last longer and provide greater stopping power, but damage your BMW 525i brake rotors faster. Non-metallic or organic brake pads, also called "soft" brake pads, must be replaced more often, but they are much friendlier to your 525i brake rotors. As long as you change your brake pads when the thickness of the lining drops to between an eighth and a quarter of an inch, your BMW 525i brake rotors will last for quite a while. However, if your brakes are grinding or pulling to one side, you may need to replace your 525i brake rotors.Look to us for a wide selection of BMW 525i brake rotors at great discount prices.
