Double Black Offroad

TeraFlex Jeep JK Brake Master Cylinder with Oversized Bore

We have a brake master cylinder with an oversized bore that has 14% more flow.  It is a recommended upgrade to provide a firmer pedal when using our Big Brake kit.  This is a great solution to a softer pedal that may appear once you have had the Big Brake Kit. 2007-2008 and 2011 JK's have a greater need and we highly recommend this cylinder for those applications.
