Review on 🔧 High-Performance ABN Brake Cylinder Hone Piston Abrasive & Finishing Products - Enhance Brake Cylinder Performance by Cameron Reed

Inexpensive but neat tool for independent work without frills. I needed a honing machine for an air pump overhaul. One of the two cylinders had a nasty scratch from which lubricating oil was leaking. This honing made it possible to remove this scratch without excessive material removal and to keep the piston ring clearance within acceptable limits. If I had any complaints it would be that the design limits rock pressure for what I needed it for but probably ok for cleaning a disc brake caliper.
