BC 1-3/4" Brake Cylinder Flex-Hone 240SC Grit - Brush Research

The Brush Research BC13424 BC 1-3/4" Brake Cylinder Flex-Hone 240SC Grit is a professional-grade tool from Brush Research Manufacturing (BRM), designed for precision surface finishing and cross-hole deburring in critical automotive and industrial components. Manufactured in the USA, this Flex-Hone is engineered to deliver superior bore finishes, essential for optimal system performance and extended component life.

Key Features

• Optimized for 1-3/4" Cylinders: Specifically designed for reconditioning 1-3/4 inch (45mm) brake and wheel cylinders, ensuring a precise fit and effective operation for critical automotive braking systems.
• 240SC Silicon Carbide Abrasive: Utilizes 240SC grit Silicon Carbide abrasive, an aggressive material effective on mild steel, stainless steel, and cast iron, which removes peaks and creates a desirable plateaued finish for optimal sealing.
• Flexible, Self-Centering Design: Features resilient abrasive globules with independent suspension that automatically self-center, self-align, and self-compensate for wear within the bore, ensuring uniform pressure and a consistent, non-directional finish without specialized alignment tools.
• Controlled Surface Condition: Produces an oil-holding crosshatch pattern and a true plateau finish, free of cut, torn, and folded metal. This critical surface promotes rapid ring seating, superior oil control, reduced seepage in hydraulic and pneumatic applications, and significantly extends seal life.
• Effective Cross-Hole Deburring: Capable of simultaneously finishing internal surfaces and deburring cross-drilled holes and ports, crucial for preventing premature wear and improving component longevity.

Applications

• Automotive Brake Systems: Indispensable for rebuilding and reconditioning brake master cylinders, wheel cylinders, and calipers, ensuring proper seal function and reliable brake performance.
• Hydraulic and Pneumatic Systems: Suitable for various hydraulic and pneumatic cylinders and valve bodies requiring refined internal surface finishes for optimal sealing and consistent function.
• Valve Guides: Enhances the surface finish of valve guides for improved engine performance and reduced wear over time.
• General Industrial: Applicable for deglazing and surface finishing in various small-diameter bores across manufacturing and maintenance sectors.
