If your car uses a disc braking system, it is equipped with BMW 328 brake rotors. Your 328 brake rotors, also referred to as brake discs, work with your brake pads to bring your car to a safe and controlled stop. Basically, your BMW 328 brake rotors are metal discs that are mounted in the U-shaped channel of your brake calipers.
The 328 brake rotors spin with your wheels. When you press down on your brake pedal, hydraulic brake fluid transmits the pressure to your brake calipers.
The brake caliper pistons squeeze inward, bringing the brake pads floating on top of them in to contact your BMW 328 brake rotors. Friction is created between the brake pads and the 328 brake rotors, which serves to slow and stop the rotational motion of your wheels. Since they are moving parts, your BMW 328 brake rotors are subject to wear and tear through normal use. The degree of wear your 328 brake rotors experience often depends on the condition of your brake pads. If you do not change your brake pads often enough, the lining of the pads will wear down and allow your BMW 328 brake rotors to scrape against the metal backing plate. Also, your car may have metallic brake pads installed, which causes more wear and tear on your 328 brake rotors than the more common organic brake pads. In order to ensure a long life for your BMW 328 brake rotors, you should make sure to keep up with your brake pads and change them when the thickness of the lining drops below a quarter of an inch. Also, if you end up needing to change your 328 brake rotors, be sure to install new pads at the same time.You can pick up a new set of BMW 328 brake rotors along with the pads right here in our extensive online catalogue.
