    Expert Installation & Field Note

    Based on our shop experience specializing in heavy-duty brakes since 1985: The 1.5-inch bore size is designed for maximum fluid displacement in high-capacity systems. When installing on heavy equipment or fleet vehicles, ensure the pushrod alignment is perfectly centered to prevent premature seal wear. Our Bexar Pro units are bench-tested for high-cycle durability to meet the demands of rigorous industrial operation.

    ⚠ CRITICAL: Verify Specifications

    To ensure safety, verify that this master cylinder’s 1.5-inch bore size and 1/2-20 INV outlet match your existing unit exactly. Mismatching specifications can lead to dangerous braking performance.
