- Self-centering, self-aligning, and self-compensating for tool wear, to reduce set-up time and costs and the need for special operator training
- A soft cutting action to create a plateau finish through a low-temperature abrading process that exposes undisturbed base metal, to help produce a long-wearing surface
- Grit size ranges from 120 to 320; higher grit numbers are finer, to help create a smooth surface finish
- Order by actual bore size as the tool is produced oversized
- Silicon carbide is more aggressive and cuts faster than aluminum oxide

Flex-Hone BC-series abrasive bead style brushes for brake cylinders, hydraulics, and valve guides, have globe-shaped abrasive points on an independent suspension for self-centering, self-aligning to the bore, and self-compensating for wear. This reduces set-up time and costs and the need for special operator training, as well as ensuring precise control of finish parameters. The resilient, flexible honing tool has a soft cutting action to create a plateau finish, where surface irregularities are reduced, while retaining a cross-hatch suitable for oil retention; the plateau finish increases the bearing area of the surface. Order by actual bore size as the tool is produced oversized.
Using the Flex-Hone low-temperature abrading process exposes undisturbed base metal, to help produce a long-wearing surface by removing cut, torn, and folded metal. The final surface of the metal part is optically smooth and has significantly reduced fragmented, amorphous, or smeared metal from previous operations. Cylinder hones are suitable for use deglazing, surface finishing, and deburring on cylinders, as well as cross hole deburring, port radiusing, and edge blending on items such as firearm chambers, musical instruments, combustion chambers, air compressors, pumps, valve bodies, valve guides, and brake cylinders. Use by hand or in NC/CNC equipment. NC-style tools can be used on both the older Numerical Control (NC) machines, which are programmed using physical media such as magnetic tape, and the newer CNC (Computer Numerical Control) machines, which are programmed using computers.
Abrasives are used for a variety of applications from shaping a part to fine finishing, depending on the grit size. Low grit numbers like 40 are coarse and are used for removing excess material and shaping a part. High grit numbers like 400 are fine and help to create a smooth surface finish. Silicon carbide is a sharp, aggressive grain that offers high penetration, fast cutting, and high material removal even under light pressure. It is commonly used with softer materials like brass, plastics, and rubber, and abrasive materials like glass and enamel, but can wear out faster than aluminum oxide when used on wood.
Brush Research Manufacturing Co., headquartered in Los Angeles, manufactures tools in the United States, and has been in operation since 1958. The company specializes in ball hone abrasives and industrial brushes for honing, a type of precision surface finishing. Brush Research meets ISO 9000 certification for quality.

I have never honed a cylinder before in my life and with this I did it perfectly the first time. It's hard to beat that.
After stripping some screws trying to get the thing took apart, I discovered the piston was quite stuck in the chamber - which required me to drill through the top of the piston, insert a metal screw and pry the b***h out with a crowbar. What I found in the chamber was nothing short of horrific - a nice thick black coating of whatever the brake fluid turned into after all these years. It looked like carbon, and it was impossible to get scrubbed out with brass bore cleaners or soaked out with anything I had available (which is a lot of stuff).
I searched around for potential replacements on eBay, but there was nothing that looked like it would be a 'sure buy' that would work - especially for the money these people were asking. So, I have to make this work...
Eventually I gave up on the fruitless manual labor and tried to find another solution. Stumbled across 'honing engine cylinder' and started looking for really small honing tools (5/8" or 16 mm). Found this, got it today, attached it to my drill, doused the cylinder and this tool with brake fluid for lubrication and let it go to work....
Freaking awesome results!!!! I got the 120 grit one, so once I get the OEM rebuild kit here, I will do a test fit and if things look snug, I will get the 320 grit brush and finish it up.
Very happy to finally be able to move past the roadblock and get onto other stuff on this bike!!!
ps add a little oil. good product.
amazon shipping as usual was fast did overnight it was there by 10 am.
