F5UZ2261A Brake Wheel Cylinder for Ford

Ford's special F5UZ2261A brake cylinder is a hydraulic brake core component designed for Ford's various SUVs and high-performance models. The cylinder adopts an integrated casting process, and the cylinder body is made of high-strength aluminum alloy, which not only reduces the unsprung mass but also improves the heat dissipation efficiency. As the core execution unit of the disc brake system, its working principle is similar to that of the Ford electric rear brake cylinder. It drives the piston to squeeze the brake pad through the hydraulic changes in the cylinder to achieve precise transmission of braking force. At the same time, the built-in dust cover and guide pin self-lubricating system can withstand the high temperature and dust erosion caused by frequent braking.

From the manufacturing standard, F5UZ2261A strictly follows Ford's Q1 supplier management system, and the production process covers four major links: precision casting, CNC machining, ultrasonic cleaning and dynamic testing. The inner wall of the cylinder adopts mirror polishing technology, and the surface roughness is controlled within Ra0.4μm. Combined with the double-layer sealing structure of the fluororubber sealing ring, it can maintain stable sealing in an environment of -40℃ to 180℃.

The wheel cylinder uses VIN code intelligent matching technology and is compatible with 2018-2023 Ford Explorer 2.3T/3.0T models, Edge ST-Line and many other models. During installation, special attention should be paid to the anti-twist protection of the brake oil pipe interface. After removing the old wheel cylinder, the oil line port should be immediately blocked, and the fixing bolts should be tightened with a torque wrench with a standard torque of 28-32Nm. The F5UZ2261A wheel cylinder has been structurally strengthened to meet the heavy-load characteristics of American cars. Its piston diameter reaches 45mm, which is about 15% larger than the basic model. It can shorten the braking distance by 8%-12% when combined with ventilated brake discs.
