BC 5/8" (16MM) Brake Cylinder Flex-Hone Grit - Brush Research

The Brush Research BC5812 5/8" (16mm) Brake Cylinder Flex-Hone is a purpose-built tool designed for the precise reconditioning and finishing of small brake and hydraulic cylinders. This professional-grade honing tool is engineered to deliver a consistent plateau finish, which is crucial for optimizing sealing, ensuring efficient fluid retention, and extending the operational life of rebuilt automotive and industrial systems.

Key Features

• Targeted 5/8" (16mm) Diameter: Specifically sized for reconditioning small wheel cylinders and similar bores commonly found in drum brake systems on passenger cars, light trucks, and fleet vehicles.
• Self-Centering Design: Its flexible construction automatically aligns within the bore, distributing pressure evenly to minimize taper, out-of-round conditions, and potential operator error.
• Advanced Abrasive Globules: Flexible abrasive balls conform to minor bore imperfections, creating an ideal plateaued surface with an effective cross-hatch pattern for superior fluid and lubricant retention. This process removes cut, torn, and folded metal, reducing peaks to a consistent height.
• Controlled Cutting Action: Effectively deglazes, cleans, and refines cylinder surfaces without aggressive stock removal, preserving critical cylinder dimensions and integrity.
• Professional-Grade Durability: Constructed for repeated use in demanding environments such as automotive brake service bays, machine shops, and hydraulic rebuild operations.

Applications

• Reconditioning and deglazing automotive drum brake wheel cylinders prior to seal or cup replacement.
• Finishing small hydraulic and pneumatic cylinder bores in various industrial equipment.
• Preparing bores for new pistons, rings, cups, or seals during comprehensive brake and hydraulic system rebuilds.
• Maintenance and quality control in remanufacturing facilities where consistent, repeatable bore finishes are essential.
