BC 7MM (.276") Brake Cylinder Flex-Hone Grit - Brush Research

The Brush Research BC7M12 BC 7MM (.276") Brake Cylinder Flex-Hone Grit is a specialized tool engineered for the precise surface finishing and deglazing of automotive and industrial brake cylinders. Designed for professional technicians, this honing tool efficiently removes surface imperfections like rust, corrosion, and microscopic burrs, creating an optimal cylinder wall finish for superior piston seal seating and dependable braking performance. It is an essential component for any workshop focused on brake system overhauls and reconditioning.

Key Features

• Precision 7MM Sizing: Engineered specifically for 7MM (.276") diameter brake cylinders, ensuring an exact fit and consistent, uniform honing action across the bore.
• Optimized Surface Finish: Delivers a consistent cross-hatch pattern, crucial for proper lubrication retention, effective seal break-in, and preventing fluid bypass.
• Professional-Grade Abrasive: Features high-quality abrasive grit for controlled material removal, ensuring durability and extended tool life even in demanding professional environments.
• Self-Centering Flexibility: The flexible design naturally conforms to cylinder imperfections, providing even pressure distribution throughout the bore for a consistent, precise finish.
• Enhanced Seal Performance: Prepares cylinder walls to significantly improve the sealing interface for new piston seals, minimizing leaks and extending the operational life of reconditioned components.

Applications

The Brush Research BC7M12 Flex-Hone is an indispensable tool for reconditioning brake and small hydraulic cylinders across a diverse range of vehicles and industrial equipment. It is commonly utilized by professional mechanics and technicians for:

• Automotive Brake System Overhauls: Restoring master cylinders and wheel cylinders in cars, light trucks, and SUVs to factory specifications.
