Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: The 1-1/2-inch bore is a high-volume unit that requires precise pushrod alignment to function correctly. When installing in industrial environments, always verify that your linkage allows the piston to return fully to the stop; failure to do so will result in brake drag and overheating. Ensure a thorough system bleed after installation.
⚠ CRITICAL: Verify Specifications
