Teraflex Brake Master Cylinder Kit with Oversized Bore - Jeep JK & JKU 07-11

The TeraFlex BRAKE MASTER CYLINDER KIT With OVERSIZED BORE complements the oversized caliper pistons in our FRONT BIG BRAKE KITS (TX4303420) and is highly recommended for 2007-2011 JK Wrangler and JKU Wrangler Unlimited models. The oversized bore flows 14% more volume compared to the factory master cylinder for a firm pedal feel. Not necessary for 2012-2018 JK Wrangler and JKU Wrangler Unlimited models.
