The Hydraulic Cylinder Displacement Gauge measures and checks the movement of the piston inside master cylinders and brake cylinders during service and inspection work. It helps the user understand how far the piston travels while the system is operated, which supports correct functional evaluation. By providing a clear measurement of piston movement, the gauge allows issues related to improper travel to be identified early. Accurate piston movement measurement helps ensure correct system response during operation.Attributes:• Measures piston movement during service inspection activities.• Helps users verify correct piston travel within hydraulic cylinders.• Supports accurate evaluation of master cylinder operation.Applications: The Hydraulic Cylinder Displacement Gauge is located on master cylinders and brake cylinders, where it measures piston movement during operation, allowing users to verify correct travel and functional response.
