Did you know that TeraFlex also offers upgraded brake kits for JK Jeep Wrangler and JKU Jeep Wrangler Unlimited models? These kits are designed to increase stopping power over the stock braking system. A must when you begin adding larger wheels and tires as well as other off-road gear and accessories. 

.   

Front Big Brake Kits

The JK/JKU TeraFlex Front Big Brake Kit is a must for JK Wrangler and JKU Wrangler Unlimited models requiring increased braking performance with oversized – and heavier – wheels and 33-35” tires. This simple bolt-on upgrade doesn’t require cutting, welding, or adapters.

The oversized 56mm dual-piston calipers with composite-resin, semi-metallic pads and larger 13.3” rotors (vs. 11.9” stock rotors) provide superior stopping power with less heat buildup and fade. The standard mill balanced and vented rotors offer excellent heat dissipation, while the available slotted rotors provide maximum heat dissipation.

Performance Big Rotor Kits

These JK/JKU TeraFlex Performance Big Rotor Kits are an affordable upgrade for JK Wrangler and JKU Wrangler Unlimited models requiring increased braking performance with oversized – and heavier – wheels and 33-35” tires. This simple bolt-on upgrade doesn’t require cutting or welding.

The brake caliper relocating anchor brackets allow the installation of larger 13.3” front rotors (vs. 11.9” stock rotors) or 13.5” rear rotors for superior stopping power with less heat buildup and fade. The standard mill balanced and vented rotors offer excellent heat dissipation, while the available slotted rotors provide maximum heat dissipation.

Brake Master Cylinder Kit

.  

The TeraFlex JK/JKU Brake Master Cylinder Kit w/ Oversized Bore complements the oversized caliper pistons in our Front Big Brake Kit. The oversized bore flows 14% more volume compared to the factory master cylinder for a firm pedal feel.

Highly recommended for 2007-2011 JK Wrangler and JKU Wrangler Unlimited, but not necessary for 2012-2018 JK Wrangler and JKU Wrangler Unlimited models.

Rear Brake Line Extension Kit

The JK/JKU TeraFlex Rear Brake Line Extension Kit allows the factory rear brake lines to be retained on JK Wrangler and JKU Wrangler Unlimited models with up to a 3” lift. The extension bracket bolts to the frame effectively lowering the mounting point of the hard brake line by 3.25 inches. Doesn’t require opening up the brake line system.
