Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: The 1-1/4-inch bore size is a high-displacement specification often found in heavy equipment. When installing the M54484, check your pushrod alignment to ensure the piston travels squarely within the bore. Misalignment is the leading cause of internal seal bypass in industrial fleet applications. Always verify that the 3/8-NPT threads are clean and use appropriate sealant to prevent hydraulic leaks.
⚠ CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-1/4-inch bore size and 3/8-NPT outlet match your existing unit exactly before purchasing.
