Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: The 1-1/8-inch bore size is common in high-capacity fleet and industrial designs where consistent stopping power is non-negotiable. When installing the M1671433, precision pushrod alignment is critical to ensure the internal piston travels squarely within the bore. Side-loading or improper rod adjustment is the leading cause of internal seal bypass. Always flush the entire hydraulic circuit with fresh fluid to prevent contamination of the new seals.
⚠ CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-1/8-inch bore size matches your existing unit exactly before purchasing. Professional installation is highly recommended.
