Jeep TJ LJ Unlimited 1999, Rear Disc Brake Kit by TeraFlex®. This disc brake kit is intended for use as a bolt-on upgrade to replace factory Jeep drum brakes. Upgrade your Jeep's brakes with a kit from TeraFlex. Larger-diameter wheels and tires mean your brakes have to work harder, so you should upgrade just to maintain your original braking ability. Add weight from a bunch of gear, armor and modified parts, and a long downhill could leave you without enough braking.
- Oversized twin-piston caliper
- More clamping force
- Increased surface area
- Decreased brake fade
- 13.3" mill-balanced vented rotors
- Dual-pattern drilled to fit 5 on 5" and 5 on 5.5" bolt pattern
- Semi-metallic pads
Hanging a set of huge tires can buy you a lot of ground clearance and a lot of grip, that's certain. But did you ever think of the affect it might have on your brakes? You've changed out the stock differentials to reflect the extra diameter of those big tires, because the extra diameter sucked up most of the torque available. Think about it: the extra leverage from the big rubber has the same effect on your brakes. One mod that goes hand-in-hand with big tires is big brakes. TeraFlex's Big Brake Kit, whether you choose the straight, vented rotors or the slotted ones, gives you not only a larger-diameter, heavier disc that can dissipate more energy, but a bigger caliper with bigger pads for more braking actions. With two massive pistons squeezing the disc instead of one, you'll be able to stop shorter, feather the brakes coming down a hill more accurately, and have better pedal feel. The slotted rotors will provide better braking action when wet, because the slots wipe the water off the surface of the disc.
Adding a second pair of discs to the rear will only improve your braking even further. Be aware that upgrading your brakes often requires upgrading the master cylinder and proportioning valve as well. The larger pistons, and more of them, require a master cylinder that moves more fluid, or it will feel spongy and travel too close to the floor.476.89 671.64

TeraFlex has been professionally involved with Jeeps since the 1950s and that experience taught them how to make them perform their best. TeraFlex was started in the fall of 1996 to meet the needs of the growing market for heavy duty off road equipment and suspension enhancements. And they've maintained a dominant hold on the market since then. TeraFlex was the first aftermarket manufacturer with a suspension system for the TJ Wrangler, and is still the only aftermarket company to offer a solution for the venerable 231 transfer cases low range gearing. In 2001, the entire off road industry was stunned at the CRD60 - an off-road-specific high-pinion 60 differential that took innovation to a new level, reinforcing their position in the industry.
