Expert Installation & Field Note

Based on our shop experience specializing in heavy-duty brakes since 1985: The 1-5/16-inch bore is essential for large commercial vehicle pressure requirements. Due to the two distinct outlet thread sizes (1/2-20 and 9/16-18), meticulously verify which hydraulic lines connect to which port on your original cylinder before removal. Improper plumbing or poor pushrod alignment will lead to brake imbalance and premature seal wear in industrial environments.

⚠ CRITICAL: Verify Specifications

To ensure safety, verify that this master cylinder’s 1-5/16-inch bore size and dual 1/2-20 & 9/16-18 INV outlets match your existing unit before purchasing.
