Misalignment is a primary cause of uneven internal seal wear, which can lead to premature bypass in fleet and industrial applications. Always bench bleed the unit before final installation to ensure a firm pedal and perform a complete system flush with fresh fluid to protect the precision 1-1\/8-inch bore galleries.<\/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\/8-inch bore size<\/strong> and <strong>1\/2-20 INV outlet<\/strong> match your existing unit exactly before purchasing.
