1-1/2" x 5/8" Scotch-Brite™ Roloc™ Pro Brake Hub Cleaning Disc - 3M Automotive

The 3M Automotive 21713 Scotch-Brite™ Roloc™ Pro Brake Hub Cleaning Disc provides professional technicians with an efficient solution for preparing brake and wheel-mounting surfaces. This 1-1/2" x 5/8" non-woven disc swiftly removes corrosion, promoting proper component seating and helping to maintain essential dimensions without damaging critical parts. It is engineered for consistent performance across various automotive applications.

Key Features

• Scotch-Brite™ Non-Woven Construction: Utilizes sharp silicon carbide mineral to effectively cut through rust, scale, and corrosion on hubs and rotor-mating surfaces. This design conditions the surface for proper rotor, drum, and wheel seating, which helps minimize runout, vibration, and torque variation, while preventing gouging and excessive metal removal.
• Roloc™ Quick-Change Interface: The 21713 3M disc securely locks into Roloc™ holders, enabling rapid changeover between vehicles. This quick-change capability enhances productivity in flat-rate and high-volume brake bays by minimizing setup time.
• Pro-Grade Durability: Built to withstand repeated use on passenger cars, light trucks, and SUVs, this cleaning disc maintains consistent cleaning action over multiple brake jobs, ensuring reliability for professional mechanics.
• Compact 1-1/2" Diameter: Precisely sized to reach tight areas around studs and hub faces, ensuring thorough cleaning where larger discs cannot safely access. Its hollow center allows the disc to slide over studs without causing damage.

Applications

• Cleaning brake hubs and rotor-mating surfaces before installing new rotors or drums on passenger cars, light trucks, and SUVs.
• Removing rust and corrosion from wheel-mounting faces to promote even clamp load and reduce comeback complaints related to vibration or misalignment.
• General metal surface conditioning on small, flat, or lightly contoured areas where controlled, non-aggressive cleaning is required.
