Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985, the most common cause for failure after a rebuild is the over-extension of the internal cup during bench bleeding. 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.
CRITICAL: Verify Specifications
