DBC 3-1/8" (79mm) Brake Cylinder Flex-Hone 120SC Grit - Brush Research

The Brush Research DBC 3-1/8" (79mm) Brake Cylinder Flex-Hone 120SC Grit, model DBC31812, is a professional-grade abrasive tool meticulously engineered for deglazing and finishing brake cylinders. This compact, self-centering, and self-aligning honing tool is designed to restore cylinder walls to an optimal surface finish, crucial for superior brake performance, proper piston seal seating, and extended component longevity. It effectively removes rust, corrosion, and glazing, preparing the surface for efficient oil retention.

Key Features

• Optimal Surface Restoration: Develops a plateau finish that removes fragmented or smeared metal, ensuring a metallurgically clean surface for enhanced seal performance and extended component life. This process reduces Ra, Rk, and Rpk values while maintaining Rvk and Vo volume for oil retention.
• Consistent Cross-Hatch Pattern: Utilizes durable 120SC (Silicon Carbide) abrasive globules to achieve a consistent cross-hatch pattern, promoting excellent oil retention and reduced friction.
• Compact Design: The shorter, more compact tool body allows for efficient operation in confined spaces, making it ideal for various brake cylinder applications.
• Contaminant Removal: Effectively eliminates rust, corrosion, and glazing from cylinder walls, preventing premature wear and improving hydraulic efficiency.
• Durable Construction: Built with high-density nylon filaments laminated with abrasive, ensuring resilience and consistent performance in demanding professional environments.

Applications

This Flex-Hone tool is widely used by professional technicians and mechanics for a variety of applications, including:

• Deglazing and finishing automotive disc brake cylinders.
• Restoring motorcycle and ATV brake cylinders.
• Preparing hydraulic ram cylinders and pneumatic cylinders requiring precise surface conditioning.
• Deburring cross-drilled holes in various metal components to ensure clean, radiused intersections.
