⚠ CRITICAL: Verify Specifications

To ensure safety, verify that this 1.75-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 this casting number was utilized across multiple assembly configurations.

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; even a slight misalignment can lead to premature seal wear under high-pressure fleet operation. For GM/Chevrolet applications, verify your pedal rod depth matches the primary piston pocket to ensure full stroke return.
