This hydraulic filter element is installed in the brake system circuit of the host tractor. It removes particulate contamination from the hydraulic fluid before it reaches the brake control valves and actuators. A clogged filter reduces flow to the braking system, which can cause a spongy pedal feel or delayed brake engagement. The manufacturer machines the thread and seal face to match the housing port, ensuring the element seats correctly and the bypass valve operates at its intended cracking pressure. Replace the sealing washer on reinstallation.
