130702000253A002 Brake Piston Sany SAT40C Articulated Dump Truck spare parts

130702000253A002 is an original equipment manufacturer (OEM) brake piston, suitable for wheeled construction machinery and heavy-duty mining dump equipment, and is integrated into the brake caliper assembly. As a core transmission component of hydraulic braking, it relies on hydraulic thrust to extend and retract, pressing the brake pads against the brake disc to complete deceleration and stopping. It can improve problems such as soft braking, slow response, uneven braking force, and weak braking on one side, and avoid faults such as piston jamming, corrosion, and pressure decay, ensuring the sensitivity and stability of the braking system.
This product is made of high-strength precision alloy and machined in one piece. It undergoes CNC precision grinding, surface hardening, sealing adaptation, stress relief, and anti-corrosion and rust prevention processes. The column is smooth and dense, with a balanced hardness and toughness, exhibiting excellent resistance to pressure and impact, wear and fatigue, and deformation. Original factory precision tolerances ensure a tight seal, smooth expansion and contraction without obstruction, and long-term resistance to high-pressure braking and high-frequency reciprocating motion. It eliminates problems such as scoring, pressure leakage, and corrosion failure, stabilizes braking pressure output, improves braking response accuracy, extends the life of the braking assembly, and reduces equipment maintenance costs.
