FLEX-HONE BC11232 Brake Cylinder Hone, 1-1/2" Bore Diameter, 320 Grit Silicon Carbide

FLEX-HONE BC11232 Brake Cylinder Hone, 1-1/2" Bore Diameter, 320 Grit Silicon Carbide

The Brush Research BC11232 Flex-Hone is a precision brake cylinder honing tool designed for 1-1/2" bore diameter applications. Featuring 320 grit silicon carbide abrasive, it produces a fine plateau-style cross-hatch finish that enhances lubrication retention, reduces fluid leakage, and improves seal performance in brake and hydraulic cylinders.

• Features:
  • Self-centering and self-aligning brush-style hone for consistent wall contact
  • 320 grit silicon carbide abrasive delivers a fine finish (approximately 18–30 µin Ra)
  • Creates a non-directional plateau finish ideal for improving seal life and oil retention
  • Compact and flexible design for easy use in brake and wheel cylinders, valve guides, and small hydraulic bores
• Specifications:
  • Bore Diameter: 1-1/2"
  • Abrasive Material: Silicon Carbide
  • Grit: 320 (Extra-Fine)
  • Abrasive Length: 3"
  • Overall Length: 8"
  • Stem Diameter: 0.245"
  • Recommended Speed: 800–1200 RPM
  • Typical Surface Finish: 18–30 µin Ra
  • Applications: Brake and wheel cylinders, valve guides, small hydraulic and pneumatic bores

The FLEX-HONE BC11232 can also be referred to as 1-1/2" bore hone, BC11232 flex hone, brake cylinder hone, plateau honing brush, and silicon carbide brake hone.

Brush Research Manufacturing has over 60 years of expertise in precision surface finishing tools. Their Flex-Hone line is trusted by technicians across automotive, hydraulic, and industrial applications for achieving consistent, high-quality finishes.

Q: What bore diameter is this hone designed for?
A: The BC11232 Flex-Hone is specifically designed for use in 1-1/2" bore diameter brake and hydraulic cylinders.

Q: What finish quality does the 320 grit provide?
A: It produces a fine plateau finish in the range of 18–30 µin Ra, ideal for sealing surfaces and oil retention.

Q: Can I use this hone with a handheld drill?
A: Yes—use with a handheld drill or drill press at speeds between 800 and 1200 RPM, with proper honing oil.

Q: What materials is this hone suitable for?
A: It works well on steel, cast iron, stainless steel, and other metals used in brake cylinder manufacturing.

Q: What lubricant should be used?
A: Use oil-based honing lubricants to protect the abrasive bond and ensure a smooth, consistent finish.
