Since this unit does not include a pedal rod, ensure your existing rod is free of pitting or bends before installation. Proper pushrod alignment is critical to ensure the piston travels squarely within the bore, preventing internal bypass and ensuring a firm pedal response.<\/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.<\/p>\n<\/div>\n<div class=\"sleek-banner\" style=\"display: flex; align-items: stretch; border-radius: 6px; overflow: hidden; background: #c00000; min-height: 120px; border: 1px solid #c00000;\">\n<div style=\"background: #ffffff; padding: 20px; flex: 1; display: flex; justify-content: center; align-items: center; border: 8px solid #c00000;\"><img decoding=\"async\" style=\"width: 240px; height: auto; max-width: 100%;\" src=\"2026\/03\/bexar-pro-01-1.png\" alt=\"Bexar Pro Components\" \/><\/div>\n<div style=\"flex: 1.2; padding: 25px; color: #ffffff; display: flex; flex-direction: column; justify-content: center; text-align: left; background: #c00000;\">\n<p style=\"margin: 0; font-size: 13px; text-transform: uppercase; opacity: 0.9; letter-spacing: 1.5px; font-weight: 600;\">Bexar Pro Components<\/p>\n<p style=\"margin: 0; font-size: 28px; font-weight: 800; letter-spacing: 1px; color: #ffffff; text-shadow: 1px 1px 2px rgba(0,0,0,0.2);\">SKU: M3648304<\/p>\n<\/div>\n<\/div>\n<div style=\"text-align: center; margin-top: 25px;\"><a class=\"cta-button\" style=\"background: #333; color: #fff; padding: 14px 28px; text-decoration: none; border-radius: 4px; font-weight: bold; display: inline-block; font-size: 14px;\" href=\"https:\/\/automotivebrakeandclutch.com\/master-cylinder-replacement\/\">Official Master Cylinder Installation Guide<\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>New Brake Master Cylinder 1-1\/8-inch bore size FE2539 29943-C B288 Bexar Pro Components: Heavy-Duty Reliability for Fleet &amp; Industry.
