47550-12090 Brake Wheel Cylinder for Geo

47550-12090 Brake Wheel Cylinder For Geo is a core brake component designed for passenger cars. As the execution terminal of the hydraulic brake system, its core function is to convert the pressure transmitted by the master cylinder into mechanical thrust through hydraulic energy, drive the brake pads and brake discs/drums to produce friction to achieve deceleration. This component is cast with HT200 gray cast iron, the surface is treated with electrophoresis anti-rust, the piston diameter is 3/4 inches, and it can withstand 32MPa hydraulic pressure.

47550-12090 Geo brake wheel cylinder adopts a single piston structure, and the piston seal is made of fluororubber. The temperature range covers -40℃ to 180℃, which is suitable for frequent urban congestion. The guide pin system is nitrided and hardened, and with the double-layer dust cover design, it effectively blocks the intrusion of mud and sand and reduces the risk of jamming. Test data shows that the friction coefficient stability of the wheel pump is better than the industry standard of 0.38-0.42 after 500 consecutive brakings, and the temperature fluctuation is controlled within ±12℃.

As an important product in the global supply chain, the cast iron housing of the 47550-12090 wheel pump can reduce the thermal attenuation effect after continuous braking by optimizing the heat dissipation structure and cooperating with the ventilated brake disc design.
