The 3M™ Brake Hub Cleaning Disc Holder is used to attach and hold brake hub cleaning discs to die grinders or right angle disc sanders. 3M™ Brake Hub Cleaning Disc Holder and associated discs are designed to remove rust and corrosion from metal surfaces, particularly around wheel studs on brake drums or rotors.
Cleaning the brake's rotor and hub is an important step in reducing the potential for misalignment. Being proactive helps avoid rotor disc thickness variability and misalignment, which can lead to braking problems like pedal pulsation when stopping or premature brake pad wear. As corrosion may inhibit overall brake performance, 3M™ Brake Hub Cleaning Products were designed to give operators a quick and effective means of removing rust from the brake's rotor and hub.
