4R3Z-7A543-AA -> 9R3Z-7A543-A is the checked early master chain. 2011-2014 BR3Z-7A543-A is a separate application, not the next universal revision. 6R3Z-7A512-C -> BR3Z-7A512-A applies to the checked line.
Fitment
Separate cracked master pushrod/eyelet, pedal/bracket movement, hydraulic line, air in system, release bearing/slave and clutch mechanical faults. Confirm manual transmission, year group, engine and VIN.
Aftermarket options
Genuine masters, OEM plastic line and braided line upgrades exist. A pushrod repair part does not replace a leaking master or correct pedal/bracket damage.
Before you buy
The 2005-2010 and 2011-2014 master cylinders are separate. Diagnose the master connection, pedal/bracket, line, release bearing and clutch before ordering. A braided line cannot repair a cracked master or internal slave failure.
