What does a brake master cylinder do?
It converts the force from your brake pedal into hydraulic pressure, sending brake fluid through its outlets to operate the vehicle's brake circuits.
Does this master cylinder include a reservoir, sensor, or mounting hardware?
No. The package contains the master cylinder only—no reservoir, sensor, or mounting hardware is included.
Which vehicles does the M630600 fit?
It's a direct-fit replacement for the listed 2005-2010 VW Bora, 2006-2010 SEAT Leon, 2006 SEAT Toledo, 2007-2016 VW Jetta, 2010-2014 VW Golf, 2013 Golf SportWagen, and 2014-2016 VW Beetle. See the Buyer's Guide tab.
What is this master cylinder made of?
It has an aluminum housing cast to match the original part's casting material, and its rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
What are signs the master cylinder may need replacing?
A pedal that slowly sinks to the floor, a spongy feel, or unexplained brake-fluid loss can be signs. Diagnose the cause first; if the master cylinder is at fault, this unit replaces it.
