In it's stock form, the braking capacity/response on a stock Jeep is barely adequate in my opinion. As we add mods to our Jeeps, specifically weight in the form of larger tires, bumpers, winches, etc., we begin to diminish the braking capacity even further. This is one area that needs upgrading, and should be a priority for any Jeeper.
Jeep Performance Big brake kit
There are several choices on the market for upgrading our brakes. I chose to go with the factory Jeep Performance Big Brake Kit (BBK). I really like this kit as it includes an upgraded master cylinder. The parts are taken from the Dodge 1500 pick up line, and uses ceramic pads. Because the front brakes actually do most of the braking, this is a big time upgrade! Here's a look at what's in the kit. Interestingly, these brakes are standard on the European Wranglers. Not really sure why europe gets a better equipped model than we do here in America?
The kit features 13" rotors, big 2 piston calipers, and a 21 percent larger master cylinder. This will require running at least 17" wheels to clear the calipers. Because these are Mopar components, replacement parts are not hard to find. Here's a look at them installed on my Jeep...
This has been one of my favorite upgrades from the very beginning. It provides great peace of mind, knowing that the Jeep will stop when needed. I've had a few instances of having to do an emergency stop, and these brakes will momentarily lock up up a 35" and a even a 37" tire on pavement before the ABS kicks in.
Teraflex rear performance big rotor kit
Not long after I upgraded my front brakes, I decided to upgrade the rear brakes as well. I was curious to see if I could further enhance the JK(U)s braking prowess. For me, this was all about trying to improve on every aspect of my Jeeps performance. For the rear brakes, I went with TeraFlex's rear Performance Big Rotor Kit. This kit features larger 13.5" rotors, and caliper relocation brackets. Here's a look...
As part of this mod, I chose to go with EBC Yellowstuff Truck pads. Previous experience had taught me the Yellowstuff pads will provide a big performance gain.
I'm super happy with the way this turned out. The brakes have a nice balanced feel to the system. Braking performance has been increased greatly, inspiring driving confidence. Remember, when we build up our Jeeps, we need to build on a solid platform. Don't neglect upgrading your brakes beore adding weight to your Jeep!
