BC 1-1/2 Inch Brake Cylinder Flex-Hone 180SC Grit - Brush Research

The Brush Research BC11218 BC 1-1/2 Inch Brake Cylinder Flex-Hone is a professional-grade tool designed for achieving precise surface finishes in automotive and industrial brake and hydraulic cylinders. This 180SC silicon carbide cylinder hone efficiently deglazes, cleans, and establishes an optimal plateau finish in small bores, which contributes to extended component lifespan and reduced rework in demanding service environments. Its flexible design and abrasive globules ensure a consistent, uniform finish.

Key Features

• Optimized for 1-1/2" Bores: This 1-1/2" Flex-Hone is precisely sized for common wheel cylinders and various small hydraulic and clutch bores found in passenger cars, light trucks, and industrial machinery, offering versatility for diverse tasks.
• Flexible, Self-Centering Design: The unique ball-style construction allows the Flex-Hone tool to conform accurately to the bore, maintaining consistent alignment and contact for a uniform surface finish. This design simplifies setup, even in slightly worn or out-of-round cylinders.
• 180SC Silicon Carbide Abrasive: Featuring 180SC silicon carbide abrasive, known for its hardness and aggressive cutting properties, this tool effectively removes glaze, corrosion, and minor scoring. Simultaneously, it creates a controlled plateau finish that promotes proper seal seating, reduces friction, and optimizes fluid retention.
• Non-Dimensioning Refinement: The Flex-Hone refines the bore by removing microscopic peaks and surface contamination without significant material removal, thus preserving the factory bore size and geometry.
• Integrated Drive Shaft: Designed for practical use, the integrated drive shaft facilitates direct chucking into a hand drill or low-speed honing driver, making it suitable for efficient in-bay service, brake lathe stations, and bench work.

Applications

• Deglazing and finishing automotive and light truck brake wheel cylinders during rebuilds.
• Conditioning small hydraulic and pneumatic cylinder bores prior to seal replacement, improving seal performance and longevity.
• Refurbishing cast iron and steel brake components in automotive, fleet, and general industrial maintenance settings.
• Creating an optimal cross-hatch pattern for improved lubrication control and enhanced seal break-in, which extends component lifespan.
