⚠ CRITICAL: Verify Specifications

To ensure safety, verify that this 2-inch bore size matches your existing unit exactly before purchasing. Brake master cylinder reservoir material and height may vary, but the core fit and hydraulic function remain identical. IMPORTANT: Adaptors on the outlet ports may be needed to fit your specific vehicle’s existing brake lines, as these casting numbers were utilized across multiple assemblies.

Expert Installation & Field Note

Drawing on our shop experience specializing in heavy-duty brakes since 1985, we emphasize that pushrod alignment is vital. Always bench bleed the master cylinder before installation. Ensure the pushrod is perfectly centered; in 2-inch bore systems, even a slight misalignment can lead to premature seal wear under high-pressure fleet operation.
