If using the 207MK repair kit, do not install a check valve in the master cylinder unless one was present in your original core; adding a check valve to a non-valve system can cause poor pedal return. Always bench bleed the unit to purge air from the 1-1/16-inch bore galleries for a consistent, firm pedal feel in both automotive and industrial environments. ⚠ CRITICAL: Verify Specifications To ensure proper hydraulic pressure and safety, verify that this master cylinder’s 1-1/16-inch bore size and 1/2″ outlet size match your existing unit exactly. This specification determines hydraulic displacement and is vital for safe operation.
