Your BMW 325 brake rotors have the important job of stopping your car when you need to stop. 325 brake rotors are mounted at each wheel in your all-wheel disc braking system. BMW 325 brake rotors are single unit metal discs that spin along with your wheels as you drive.

When you step on your brake pedal, your 325 brake rotors are called upon to act. The force your foot exerts is transmitted through hydraulic fluid to the master cylinder, and then on to your brake calipers.

Pistons on your brake calipers squeeze inward, bringing your brake pads into contact with your BMW 325 brake rotors. Each of your 325 brake rotors has a brake pad on either side, so when the calipers bring the pads to the rotors, they respond with uniform stopping.

The friction generated between your brake pads and your BMW 325 brake rotors is the actual force that stops your car. As you can imagine, an important part of maintaining your 325 brake rotors is ensuring that your brake pads and calipers are in good working order. The lining of your brake pads is designed to wear down over time, and should be at least a quarter of an inch thick in order to function properly. Once your brake pad lining drops below that thickness, your BMW 325 brake rotors could begin scraping against the metal backing plate of your pads, which causes excessive wear and damage to your rotors. If you have been ignoring that squeaking sound from your brakes, and they have started to grind instead, you probably need new 325 brake rotors. Other signs that your BMW 325 brake rotors are worn include shuddering brakes or pulling to one side.Find the 325 brake rotors you need in our convenient online catalogue, and we will deliver them right to your door.
