BMW 528i Discs, Rotors & Hardware
Brakes are critical to your BMW 528i’s safety and performance. Regular maintenance of brakes can involve replacing worn-out discs and rotors in your luxury vehicle. You can find the right discs, rotors, and hardware for your 528i’s brake maintenance and learn more about them here.What are discs and rotors?
Discs and rotors are terms that refer to the same part. The rotor is the part of the BMW brake assembly that spins with the wheel. A brake pad is clamped down onto the rotor to slow the wheel with friction. Functioning much like bicycle brakes, a caliper presses the brake pad down onto the rotor of each wheel when the brake pedal is stepped on. The brake pads are made of a softer material that the rotors, so they wear away faster, but rotors do eventually suffer wear and tear. Grooves can develop that cause the pads not to make full contact when they are actuated.What rotors can be put on a BMW 528i?
A few types of rotors that fit the 528i model are available.
- Standard: These are the original equipment manufacturer (OEM) rotors that come standard with the 528i sedan. They are adequate for normal driving conditions, so if you mainly commute with your BMW, these are a good choice.
- High-performance: If you regularly test your BMW by towing heavy loads or you have modified it for street racing, you may want to improve its brakes with high-performance rotors. There is a variety of this type of rotor that is designed to handle the excess heat of braking at high speeds or with heavy loads behind the car. Some have slots or holes drilled into them for ventilation, and others are made of special materials like ceramic.
BMW 528i braking systems require regular maintenance because of normal wear and tear. Some common symptoms of BMW 528i discs, rotors, and hardware in need of attention are below.
- Squealing during stops: When the braking pads get close to needing replacement, they are designed to squeal when you stop the car. This is intended as an audible warning to have the brakes checked soon.
- Grinding brakes: If you hear a grinding noise when braking, this is a red flag that means you need to stop driving the car until you can have the braking system repaired. The brake pads are worn away, and the calipers are hitting the rotors. This will damage both of those parts if it is left unchecked.
- Wobbling tires: Worn rotors can cause the wheels to wriggle or wobble when you stop the car.
