Expert Installation & Field Note
Based on our shop experience specializing in heavy-duty brakes since 1985: Improper pushrod alignment is the leading cause of “spongy” pedal feel or premature seal failure. When replacing large-bore industrial cylinders, ensure total linkage alignment to prevent side-loading. Our master cylinders feature specially honed bores to resist wear under heavy cycling, providing quality you can feel with every stop.
⚠ CRITICAL: Verify Specifications
To ensure safety, verify that this master cylinder’s 1-1/4-inch bore size and 1/2-20 INV outlet match your existing unit before purchasing.
