The Brush Research MBC12M12 Flex-Hone is a precision cylinder finishing tool designed to deglaze, clean, and micro-finish brake cylinder bores. Built to a 12mm diameter with 120-grit abrasive globules, it conforms to the bore surface for a consistent, controlled finish that promotes proper brake seal seating and fluid retention.
Ideal for automotive and light-duty brake cylinder reconditioning, this flex hone is engineered to remove light corrosion, glazing, and surface imperfections without altering critical bore dimensions—helping restore braking performance and extend component service life.
