Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: This unit is shipped as the master cylinder only. It is CRITICAL that you re-use your existing pushrod to maintain the correct pedal height and travel. Improper pushrod alignment is the leading cause of spongy pedal feel or premature seal failure in dual-purpose hydraulic circuits. Always bench bleed the unit to ensure the 1-1/8-inch bore galleries are free of air before final installation.
⚠ CRITICAL: Verify Bore Size
To ensure safety, verify that your existing bore size is exactly 1-1/8-inch. This 1-1/8″ unit is the only replacement available for obsolete bore sizes like FF48468 (1-1/2″) and FF43812 (1-3/4″). Using any other configuration will lead to dangerously inconsistent pedal feel.
