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.

Specifications

The Shark Ammco Style Engine Honing Stones, model 85600, are specifically engineered for precision engine work. Each stone measures 2 1/2 inches in length and 3/8 inches in width. These honing stones feature a 220 grit abrasive, ideal for achieving a refined surface finish in engine cylinders. They are designed as a direct replacement for Ammco number 8560 finishing honing stones and are compatible with Ammco Model 8550 hones, which have a working range of 1-3/8" to 2".

Key Features

Ammco Style Compatibility: These stones are designed to integrate seamlessly with Ammco-style honing machines, ensuring broad usability and compatibility with existing equipment.
Optimal 220 Grit: The 220 grit abrasive provides a medium-fine finish, effective for removing glaze and minor imperfections while preparing cylinder walls. This grit size is commonly recommended for achieving a surface roughness suitable for cast iron or chrome piston rings.
Precision Dimensions: With a size of 2 1/2" x 3/8", these stones offer efficient contact and consistent material removal during the honing process.
Durable Abrasive Construction: Manufactured for longevity and consistent cutting performance in demanding workshop environments.

Applications

These engine honing stones are primarily used in automotive and heavy-duty applications for engine maintenance and rebuilding.

Engine Block Reconditioning: Ideal for restoring cylinder bores to optimal specifications.
Cylinder Bore Finishing: Essential for creating the appropriate cross-hatch pattern on cylinder walls, which is crucial for proper piston ring seating and oil retention.
Preparing Cylinder Walls: Effectively removes glaze and minor surface damage, preparing the cylinder for new piston rings.
Automotive Engine Rebuilding: A key component for achieving precise tolerances and surface finishes during engine rebuilds.

Benefits

Enhances Engine Performance: Proper honing with these stones promotes optimal piston ring seating, which can improve compression, reduce blow-by, and lower oil consumption.
Extends Engine Life: By creating a suitable surface finish, these stones help minimize friction and wear between piston rings and cylinder walls, contributing to the overall durability and lifespan of engine components.
Achieves Professional Finish: Delivers a consistent and high-quality bore finish required for professional engine assembly, ensuring precise clearances and efficient operation.
Improves Oil Retention: The cross-hatch pattern created by honing helps retain lubrication, which is vital for reducing friction and wear within the cylinder.
