Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: Improper pushrod alignment is the leading cause of “spongy” pedal feel or premature seal failure. On heavy machinery like motor graders, ensure total linkage alignment to prevent side-loading. Our M66177 housing uses a specialized honing process for superior bore integrity, outlasting standard industrial replacements.
âš CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-1/2-inch bore size and 2-1/2″ deep cup piston match your existing unit.
NOT for Wagner Power Masters (flat-style piston) or Mico Cylinders (flat reaction piston – See last picture). Check your internal components before ordering.
