Ensure you use short, controlled strokes. Always verify that the master cylinder bore is completely free of pitting or vertical scoring before installing the 394MK components. Precise pushrod alignment is critical to prevent premature seal wear and maintain consistent hydraulic pressure.<\/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.
