⚠ CRITICAL: Verify Specifications

To ensure safety, verify that this 1.75-inch bore size matches your existing unit exactly before purchasing. This model is specifically for Remote Reservoir configurations; ensure your vehicle is equipped with external fluid tanks. IMPORTANT: Adaptors on the outlet ports may be needed to fit your specific vehicle’s existing brake lines, as these castings were used across various heavy-duty assemblies.

Expert Installation & Field Note

Drawing on our shop experience specializing in heavy-duty brakes since 1985, we emphasize that when installing a remote reservoir master cylinder, the integrity of the supply hoses is paramount. Inspect for any signs of collapse or internal degradation that could restrict fluid flow to the 1.75-inch bore. Always bench bleed the master cylinder before installation and ensure the pushrod is perfectly centered to prevent premature seal wear in high-pressure fleet operation.
