Disc Brake Flex-Hone - 3-1/8 x 5" - 180 Grit - Brush Research

The Brush Research DBC3-1/8 Disc Brake Flex-Hone is a professional-grade tool engineered for precision surface finishing of disc brake cylinders, caliper bores, and rotor friction surfaces. Designed to meet the rigorous demands of automotive and industrial technicians, this 180-grit Flex-Hone ensures optimal braking performance and seal integrity in a wide range of passenger car and light truck applications. Its unique design creates a critical plateaued finish essential for component longevity and efficiency.

Key Features

• Precision Surface Preparation: The 3-1/8" diameter and 5" abrasive length deliver a refined, plateaued finish crucial for proper seal seating and effective friction material engagement within brake cylinders and caliper bores.
• Optimized Abrasive Action: Utilizing 180-grit silicon carbide abrasive, this tool efficiently establishes an ideal surface texture that minimizes initial fade and promotes stable friction characteristics.
• Self-Centering Flexibility: Its flexible, self-centering design allows abrasive globules to conform accurately to bore irregularities, ensuring uniform contact and consistently finished surfaces without issues like taper or over-cutting.
• Enhanced Braking Performance: Produces a consistent cross-hatch pattern vital for proper brake pad bedding, contributing to reduced noise and predictable braking characteristics.
• Professional-Grade Construction: Manufactured by Brush Research, this tool is built to withstand the demanding conditions of professional automotive shops and industrial maintenance environments, ensuring durability and consistent results.

Applications

• Deglazing and precise finishing of disc brake cylinders and caliper bores following machining, sleeving, or corrosion removal.
• Light resurfacing of rotor contact areas to address glazing, minor imperfections, and surface rust.
• Preparation of friction surfaces to facilitate optimal brake pad seating, reduce initial fade, and mitigate brake noise.
• Deburring and radiusing of edges within brake ports and passages, enhancing seal contact and minimizing stress risers.
