Brake Cyclinder Flex-Hone - 1-1/2 x 8 In - 180 Grit - Brush Research

The Brush Research BC1-1/2 Flex-Hone is a professional-grade abrasive tool engineered for precise surface finishing of brake cylinders. Designed for automotive and industrial applications, this 1-1/2 inch diameter, 180-grit honing tool effectively deburrs, deglazes, and creates a controlled plateau finish, preparing cylinder walls for optimal piston ring and seal performance.

Key Features

• Self-Centering and Self-Aligning: The flexible design ensures the hone automatically centers itself in the bore and aligns with the cylinder's axis, promoting consistent and accurate honing.
• Independent Abrasive Suspension: Each abrasive globule has an independent suspension, allowing for a soft cutting action that conforms to the bore surface and compensates for wear.
• Controlled Plateau Finish: Delivers a superior, cross-hatched surface finish that helps maintain lubrication and ensures proper seating of piston seals, critical for long-lasting brake system performance.
• Durable Professional Construction: Built for rigorous use in professional shop environments, ensuring reliability and longevity.
• Optimal Abrasive Grit: The 180-grit silicon carbide abrasive is ideal for deglazing and creating a consistent finish in automotive brake cylinders.

Applications

This versatile Flex-Hone is an essential tool for professional technicians involved in brake system overhauls and rebuilds. It is commonly used for resurfacing the internal bore of automotive brake master cylinders, wheel cylinders, and caliper bores to remove corrosion, glaze, and minor imperfections. Achieving the correct surface finish with the BC1-1/2 helps prevent fluid bypass, extends the life of seals, and restores proper braking function.
