    Increase Stopping Power. When upgrading to larger piston brake calipers your Jeep's factory master brake cylinder can leave you with a soft feeling brake pedal. A Teraflex Brake Master Cylinder with an oversized bore provides 14% greater fluid volume than stock to greatly improve pedal feel and braking performance. This oversized bore Teraflex Brake Master Cylinder is ideal for use with Teraflex's Big Brake Kit (part# TER4303400) or other aftermarket big brake kits.

    Premium Quality Construction. Cast from premium quality aluminum for strength, this Teraflex Master Brake Cylinder features factory style connections with high-quality EPDM rubber compound seals. Manufactured to strict engineering quality standards, Teraflex Brake Master Cylinders meet or exceed S.A.E. specifications for years of reliable leak free operation.

    Straight Forward Installation. This Teraflex Master Brake Cylinder is a direct fit upgrade for your Wrangler’s original stock master cylinder, so it simply bolts into place. Seeing that installation requires bleeding the brake system professional installation is highly recommended.

      Big brake, mannual hub and 8 lug conversation kit.

      It has been the best office ornament and one of the most expensive ones I have purchased. For some reason I cannot get any form of an answer from anyone not even Teraflex about the full floating rear axle 8 lug conversion kit that I also need and axle shafts which go into a 35-spline carrier for my JKU. This is disappointing. The parts are good looking parts but cannot be installed because they do not appear to carry axles for a 35 spline Dana 44 carrier in a JKU

      Teraflex Brake Master Cylinder w/oversized Bore

      If your going to put a big brake kit on your Jeep, you will most definitely want to get this master cylinder. Especially if you do any wheeling out west like Moab or a few other places with steep inclines where you think to your self brakes don't fail me now! Just get this master cylinder you can't go wrong in doing so..

      Big brake JK

      Delivered on time. Exactly what was advertised. Bolt right in no issues. Excellent addition to the Big Brake system much better stopping power with 37" tires.

      Great product

      Super simple to install. Coupled with my Teraflex Big Brake Kit for the front and back, my Jeep stops better then stock.
