BC 4.5MM (.177") Brake Cylinder Flex-Hone 320SC Grit - Brush Research

Specifications

• Manufacturer: Brush Research
• Model Number: BC45M32
• Product Type: Flex-Hone Tool
• Diameter: 4.5 mm (0.177 inches)
• Abrasive Material: Silicon Carbide (SC)
• Grit Size: 320
• Weight: 0.06 lbs

Key Features

• Self-Centering Design: Ensures uniform pressure distribution and consistent honing across the bore surface.
• Flexible Abrasive Balls: Conforms precisely to bore contours, effectively removing glaze and surface imperfections without altering critical bore geometry.
• Silicon Carbide Abrasive: The 320SC grit composition is optimized for creating a high-quality plateau finish on various brake cylinder materials, including cast iron.
• Precision Sizing: Specifically engineered for small diameter bores, providing an accurate fit for 4.5mm (.177") brake cylinders.

Applications

• Brake Cylinder Reconditioning: Ideal for preparing master and wheel brake cylinders to ensure optimal sealing with new cups and seals.
• Surface Preparation: Creates a non-directional plateau finish essential for proper lubrication and seal seating in hydraulic systems.
• Glaze and Corrosion Removal: Effectively cleans and deglazes internal bore surfaces, eliminating rust, contaminants, and hardened brake fluid residue.
• Automotive and Motorcycle Maintenance: Suitable for reconditioning small brake system components during repair or restoration.

Benefits

• Enhanced Braking Performance: A properly honed brake cylinder bore promotes effective seal operation, contributing to consistent and reliable braking response.
• Extended Seal Longevity: The precisely controlled plateau finish reduces friction and wear on new seals, preventing premature failure and leaks.
• Efficient Cylinder Restoration: Quickly revitalizes worn or glazed brake cylinders, restoring them to an optimal functional condition without costly component replacement.
• Improved Fluid Dynamics: Ensures proper oil retention and distribution within the cylinder, critical for smooth hydraulic function and reduced wear.
• Consistent Bore Finish: The tool’s unique design delivers a uniform and consistent cross-hatch pattern, vital for the long-term integrity of hydraulic brake systems.
