What is a brake hone used for?

A brake hone is used to resurface the inside of brake cylinders and master cylinders. It removes corrosion, rust, and minor imperfections, creating a smoother surface for the brake piston to seal against. This helps ensure proper brake function and prevents leaks.

What are the different types of brake hones available?

There are primarily two types: spring-loaded hones and rigid hones. Spring-loaded hones, like those from Brush Research, are self-centering and easier to use, while rigid hones offer more precise control over material removal. ToolSource offers 91 different brake hones to suit various needs.

What grit should I use for my brake hone?

The appropriate grit depends on the condition of the cylinder. A coarser grit is suitable for removing significant rust or damage, while a finer grit is used for finishing and creating a smooth surface. Many hones, like some from KD Tools, come with multiple grit options or replaceable stones.

How do I choose the right size brake hone for my application?

You need to select a hone with a stone diameter range that matches the inner diameter of the brake cylinder you're working on. Measure the cylinder bore accurately before selecting a hone. Many brands, including Lisle and GearWrench, offer hones in a variety of sizes to accommodate different brake systems.

What features should I look for when buying a brake hone?

Consider the hone's construction material, the adjustability of the arms, and the type of stones used. Look for hones with durable materials and easy-to-adjust tension for consistent results. Some hones, like those from Astro Pneumatic, feature flexible shafts for reaching difficult areas.

Can I use a brake hone on other types of cylinders?

While primarily designed for brake cylinders, a brake hone can be used on other small-diameter cylinders with similar material and surface finish requirements. However, ensure the hone's size and grit are appropriate for the specific application to avoid damage. Always consult the manufacturer's instructions for your specific hone.

How do I properly use and maintain a brake hone?

Always use honing oil or cutting fluid during the honing process to lubricate the stones and prevent overheating. Rotate the hone slowly and evenly, avoiding excessive pressure. After use, clean the hone thoroughly and store it in a dry place to prevent rust and corrosion. Regularly inspect the stones for wear and replace them as needed.

What brands of brake hones does ToolSource carry?

ToolSource carries a wide selection of brake hones from reputable brands, including Brush Research, KD Tools, GearWrench, Shark, Lisle, Astro Pneumatic, Cal-van Tools, and Wilmar - Performance Tool. With 91 different brake hones available, you're sure to find the right tool for your needs.

The Brush Research BC3 Brake Cylinder Flex-Hone is a professional-grade honing tool engineered to restore optimal surface finish in automotive and industrial brake cylinders. This 3 x 8 inch, 180 grit tool delivers a consistent, high-quality finish, crucial for enhancing braking performance and extending the operational life of brake system components. It's an indispensable tool for mechanics and technicians seeking precision and efficiency in cylinder reconditioning.

Key Features

Self-Centering and Self-Aligning Design: Each abrasive globule features independent suspension, ensuring the Flex-Hone remains self-centering, self-aligning to the bore, and self-compensating for wear throughout the honing process.
Plateau Finishing Technology: Creates a uniform, non-directional plateau finish by removing peaks and fragmented metal without altering bore geometry. This finish optimizes oil retention and promotes superior sealing for improved component longevity.
Soft Cutting Action: The tool's resilient and flexible nature provides a gentle yet effective cutting action that removes cut, torn, and folded metal, while preserving the integrity of the cylinder wall.
Durable Abrasive Material: Composed of 180 grit Silicon Carbide abrasive globules, making it highly effective for conditioning surfaces in mild steel, stainless steel, and cast iron brake cylinders.
Deburring Capabilities: Capable of simultaneously finishing and deburring, including removing burrs from cross-drilled holes and creating radiused intersections for enhanced functionality and safety.
Consistent Crosshatch Pattern: Produces a distinctive crosshatch pattern that aids in even lubrication distribution, reducing friction and wear in critical brake components.

Applications

The Brush Research BC3 Flex-Hone is widely utilized for honing brake cylinders across various vehicle types, including cars, trucks, and motorcycles. It is ideal for deglazing cylinder walls and restoring critical components in the automotive rebuilding industry to a like-new condition, ensuring reliable operation and increased safety. This tool is particularly effective in situations where maintaining precise bore geometry and achieving an optimal surface finish are paramount.
