When installing on industrial equipment or fleet vehicles, ensure total linkage alignment to prevent side-loading the piston. This 1-1\/4-inch bore size requires precise stroke travel to maximize cylinder life and maintain consistent hydraulic displacement. Always bench bleed the unit to purge all air from the bore galleries before final installation.<\/p>\n<\/div>\n<div style=\"border: 2px solid #c00000; padding: 20px; background-color: #fffafa; border-radius: 4px; margin-bottom: 35px;\">\n<h4 style=\"color: #c00000; margin-top: 0; font-size: 16px; text-transform: uppercase;\">\u26a0 CRITICAL: Verify Specifications<\/h4>\n<p style=\"margin-bottom: 0; font-size: 15px;\">To ensure safety, verify that this master cylinder\u2019s <strong>1-1\/4-inch bore size<\/strong> and <strong>7\/16&#8243;-24 INV outlet<\/strong> match your existing unit exactly before purchasing.
