Expert Installation & Field Note
Drawing on our shop experience specializing in heavy-duty brakes since 1985, the most common reason for a master cylinder rebuild failure is over-extending the internal cup during bench bleeding. 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 190MK components. Proper pushrod alignment is critical to prevent premature seal wear and maintain consistent pedal feel.
CRITICAL: Verify Specifications
