Expert Installation & Field Note

Drawing from our shop experience specializing in heavy-duty brakes since 1985, the most common reason for a master cylinder failing shortly after a rebuild is internal damage caused by over-extending the internal cup during the bench bleeding process. To ensure long-term reliability, always utilize short, controlled strokes. Proper pushrod alignment is also critical to prevent premature seal wear and maintain a consistent pedal feel.

CRITICAL: Verify Specifications

Components may differ from the photo due to manufacturer updates. Always verify all contents against your specific unit requirements before assembly.

⚠️ CLUTCH WARNING: For clutch master cylinder applications, do NOT install the check valve if there was not one already installed in the unit.
