Custom Performance Brakes, Pads & Rotors for BMW 4-Series
Guides & Articles
Disc brake rotors (aka 'rotors') are the actual discs that brake pads clamp onto, creating friction that slows a vehicle. Disc brake rotors bolt on over the axle hub and contain holes that allow wheel mounting bolts to pass through and rotate with the wheels. Since there are many rotor styles and designs specially created for every budget and need, we’ve listed...
Squealing noise upon brake application is actually caused by a high-frequency vibration of metal rotors, drums, or brake pad backing plates. Excess corrosion that forms over time on non-contact, outer perimeter areas of rotors and drums is a prime cause because rust is looser and less dense in nature – therefore, more likely to create resonation.
