When installing, verify that the pushrod is perfectly aligned to prevent side-loading the piston seals. Improper adjustment of the rod is a leading cause of premature failure in high-pressure applications. Always use fresh fluid to protect the internal honed surfaces of the 1-1/8-inch bore. ⚠ CRITICAL: Verify Specifications To ensure safety, verify that this master cylinder’s 1-1/8-inch bore size and dual port thread sizes match your existing unit exactly before purchasing.
