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 BC3/4 Flex-Hone is a specialized abrasive tool engineered for professional automotive and industrial technicians to achieve a precise and consistent finish in brake cylinders. Designed for optimal bore preparation, this honing tool ensures proper seating of seals and extends the service life of braking components by creating an ideal surface for new piston rings and seals.

Key Features

Resilient and Flexible Design: Features a robust, flexible construction that conforms to the bore surface, ensuring full contact and consistent abrasive action.
Independent Globule Suspension: Each abrasive globule possesses independent suspension, allowing the tool to be self-centering, self-aligning to the bore, and self-compensating for wear during operation.
Controlled Soft Cutting Action: Provides a gentle yet effective cutting action that removes microscopic peaks and valleys without altering the bore geometry significantly.
180 Grit Abrasive: Utilizes a 180-grit abrasive material, ideal for producing a specific plateau finish and cross-hatch pattern required for optimal brake cylinder performance and seal longevity.
Durable Construction: Built to withstand the demands of professional workshop environments, offering reliable performance over extended use.

Applications

The Brush Research BC3/4 Flex-Hone is primarily used for re-finishing and de-glazing the internal walls of brake cylinders. This process is crucial for:

Restoring the cylinder bore surface during brake system overhauls.
Preparing cylinder walls for the installation of new pistons and seals to ensure a leak-free and efficient operation.
Maintaining consistent braking performance in a variety of vehicle and industrial applications where 3/4-inch brake cylinders are present.
