Expert Installation & Field Note

Based on our shop experience specializing in heavy-duty brakes since 1985: When installing the M3612153, pay close attention to pushrod alignment. Misalignment is a primary cause of uneven internal seal wear, which can lead to premature bypass in fleet and industrial applications. Always bench bleed the unit before final installation to ensure a firm pedal and perform a complete system flush with fresh fluid to protect the precision 7/8-inch bore galleries.

⚠ CRITICAL: Verify Specifications

To ensure safety, verify that this master cylinder’s 7/8-inch bore size and inverted flare outlet ports match your existing unit exactly before purchasing. Correct displacement is essential for automotive and industrial safety.
