956A7644G01 is a precision aviation maintenance tool compliant with AS9100D standards and FAA/EASA regulations, dedicated to aircraft hydraulic brake systems and ground support servicing. Forged from high-strength wear-resistant alloy steel with anti-corrosion plating, it withstands -55℃ to 140℃, resisting hydraulic fluid erosion and mechanical abrasion for stable, durable performance during frequent MRO operations. Specialized in disassembling and adjusting brake caliper pistons and master cylinder valves, it features precision-machined non-slip heads with tight tolerances to avoid component damage, critical for maintaining brake pressure stability and responsive braking performance. Its compact, ergonomic design fits confined wheel well spaces, matches mainstream aviation brake specs, streamlines maintenance workflows, cuts ground downtime, safeguards brake system integrity, and is an indispensable tool for aircraft taxiing, takeoff and landing safety.
