Expert Installation & Field Note

Based on our shop experience specializing in heavy-duty brakes since 1985: The 1-1/2-inch bore size is a high-displacement specification. When installing the M3954623, verify that your pushrod alignment is perfectly centered. Improper linkage adjustment is a leading cause of internal seal bypass in industrial applications. We recommend a complete system flush with fresh fluid to protect the precision-honed bore and ensure the longevity of your new hydraulic components.

⚠ CRITICAL: Verify Specifications

To ensure safety, verify that this master cylinder’s 1-1/2-inch bore size and 1/2″-20 INV outlet match your existing unit exactly before purchasing. Accurate displacement is required for proper braking function.
