Brake Cylinder Flex-Hone - 2 x 8 In - 240 Grit - Brush Research

The Brush Research BC2240SC Brake Cylinder Flex-Hone is a professional-grade honing tool designed to deliver a consistent, high-quality surface finish in automotive and industrial brake cylinders. Measuring 2 inches in diameter and 8 inches long with a 240-grit silicon carbide abrasive, this tool is engineered for precision and efficiency, crucial for preparing cylinders for optimal sealing and performance. It ensures a reliable bore finish, essential for rebuilding brake components.

Key Features

• Silicon Carbide Abrasive: Features durable silicon carbide abrasive globules, known for their effective cutting action and ability to create a plateau finish ideal for oil retention and ring seating.
• Flexible and Resilient Design: The tool's inherent flexibility allows it to conform to the bore's exact diameter, ensuring consistent pressure and uniform honing across the entire cylinder surface.
• Self-Centering and Self-Aligning: Designed with independent abrasive suspension, the Flex-Hone automatically centers itself within the bore and aligns with its geometry, simplifying operation and reducing technician fatigue.
• Self-Compensating for Wear: As the abrasive globules wear during use, the tool naturally adjusts to maintain consistent honing pressure and effectiveness, extending its operational lifespan and ensuring reliable results.
• Professional-Grade Construction: Built for the demands of continuous use in professional automotive and industrial shops, offering durability and consistent performance.

Applications

This brake cylinder honing tool is ideal for a range of applications in professional settings. It is primarily used for reconditioning and deglazing brake master cylinders, wheel cylinders, and calipers in various automotive vehicles, including passenger cars, trucks, and heavy equipment. The BC2240SC effectively removes rust, corrosion, and embedded debris, while simultaneously creating a cross-hatch pattern that is critical for proper piston seal lubrication and longevity. This process is vital for restoring braking efficiency and preparing cylinders for new seals during rebuilds.
