Finish Line® Bicycle Disc Brake Cleaner is designed to quickly clean disc brake rotors and pads to optimize braking performance and prevent brake squeal. Its acetone-free formula decontaminates braking surfaces by removing unwanted dirt and oil residue and melting baked-on brake polish. Designed to leave no residue after application, it displaces accumulated moisture on pads or rotors. This results in improved, predictable braking and reduced squeal. Bicycle Disc Brake Cleaner is powerful enough to clean even the dirtiest rotors, yet safe enough for use on pads and around paint, carbon fiber, and plastic parts.
