During installation of the M172241, verify that the entire hydraulic system is in good condition. Improper pushrod alignment is the leading cause of spongy pedal feel; ensure total linkage alignment to prevent side-loading and maximize cylinder life.<\/p>\n<\/p><\/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 before purchasing.<\/p>\n<\/p><\/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;\">\n            <img decoding=\"async\" src=\"2026\/03\/bexar-pro-01-1.png\" alt=\"Bexar Pro Components\" style=\"width: 240px; height: auto; max-width: 100%;\">\n        <\/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: M172241<\/p>\n<\/p><\/div><\/div>\n<div style=\"text-align: center; margin-top: 25px;\">\n        <a class=\"cta-button\" href=\"https:\/\/automotivebrakeandclutch.com\/master-cylinder-replacement\/\" style=\"background: #333; color: #fff; padding: 14px 28px; text-decoration: none; border-radius: 4px; font-weight: bold; display: inline-block; font-size: 14px;\">Official Master Cylinder Installation Guide<\/a>\n    <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>New Brake Master Cylinder 1-1\/8-inch bore size FE1107 1107 Bexar Pro Components: Heavy-Duty Reliability for Fleet &#038; Industry.
