956A6046 is a precision aviation maintenance tool compliant with AS9100D standards and FAA/EASA regulations, dedicated to aircraft brake system MRO and ground support operations. Crafted from high-strength wear-resistant alloy steel, it resists extreme temperatures from -50℃ to 130℃, mechanical abrasion and aviation hydraulic fluid erosion for stable, durable performance during frequent use. Specialized in disassembling and installing aircraft main and nose wheel brake caliper pistons, it features calibrated push-pull rods with tight tolerances to avoid piston deformation or seal damage, critical for ensuring brake tightness and reliable braking performance. Its compact, ergonomic design fits confined brake bays, works with mainstream brake fixtures, streamlines servicing workflows, cuts maintenance downtime, safeguards brake system integrity, and serves as an indispensable tool for reliable aircraft ground operation and flight safety.
