To ensure long-term reliability, always use short, controlled strokes. Additionally, verify that the master cylinder bore is completely free of pitting or vertical scoring before installing the 148MK components. Proper pushrod alignment is critical to prevent premature seal wear and maintain consistent pedal feel.<\/p>\n<div style=\"border: 2px solid #cc0000; padding: 10px; margin-top: 15px;\">\n<p style=\"color: #cc0000; font-weight: bold; margin: 0;\">CRITICAL: Verify Specifications<\/p>\n<p style=\"margin: 5px 0 0 0;\">Components may differ from the photo due to manufacturer updates.
