If using the 376MK repair kit, do not install a check valve in the master cylinder unless your original core specifically used one; doing so can cause pressure trap issues. Always bench bleed the unit before final installation to ensure the 1-1/8-inch bore galleries are free of air for a smooth, consistent pedal feel. ⚠ CRITICAL: Verify Specifications To ensure proper clutch engagement pressure and safety, it is absolutely critical to physically verify that this master cylinder’s 1-1/8-inch bore size and 1/8″-27 outlet size match your existing unit exactly. Accurate displacement is required for proper function in all automotive and industrial drivetrains.
