If you own a Jeep JK, one of the essential things you will need to look for is a big brake kit. This is basically an oversized caliper used to accommodate an oversized brake pad. The main objective of these kits is to enhance the surface area of the brake pad that’s hitting the brake rotor to give you an improved braking function.
When you are looking for a big brake kit, you can expect to find a wide range of brands and models to choose from. The price may also vary widely from $1,000 to $3,000 depending upon the application. To make your decision-making process easier, we have reviewed more than a dozen products and compared them based on a number of different factors.
Read on to find a complete review of each product carefully handpicked by our team. If you are in a hurry to order, we simply suggest that you opt for the Power Stop K2798-36 brake kit. The proprietary carbon-fiber ceramic materials help to handle heavier loads while the drilled and sotted performance rotors offer maximum cooling.

#3. R1 Concepts eLINE Series Front Rear Drilled and Slotted Brake Rotors
Last but not the least, we have the eLINE Series brake rotors that promise to give immense and high-quality stopping power to your Jeep. These are made using state-of-the-art technology that makes the brake rotors last longer and ensures that the vehicle’s safety remains consistent for thousands of miles to come.
These eLINE Series brake rotors do not require any modifications, and they are designed for a direct fit. Each of these brake rotors, excluding the blank pattern rotors, comes with specialized zinc plating that is designed to protect from rust development. Although some of this corrosion protection will ultimately fade away with use, the rest of the rotor will remain protected.
Cross-drilled rotors help in minimizing the heat that accumulates on the rotor by up to 105°F. They are also chamfered, further minimizing the potential for cracking. The Diamond Slot Technology on these rotors also removes the brake and road debris, preventing the pad from glazing. This helps in extending the life of both the pad and the rotor.
Product features and specifications
- Weight: 73 lbs.
- Silver, zinc-plated exterior
- 4 brake rotors
- 8 ceramic brake pads
- Precision-drilled holes
- Diamond-slotted design
Those who have used this product have said that the installation was easy and that they stop pretty well after the initial “break-in” period. People are also happy with the good price point at which this product is available. A few customers have complained that the brakes take some time to break in after installation though and that it usually takes 400-500 miles before they get a really good grip.
The R1 Concepts eLINE Series brake rotors are a good quality product that gives you good stopping power, but you’ll have to wait for them to get properly broken in to see the difference. They generally tend to be far better than the factory brakes and perform well, too. Overall, we think this product completely delivers on what it promises.
Do big brakes last longer?
This really depend on what the items in the brake kits are made of. Many standard brakes involve the use of rubber, which wears down at the common rate found on most vehicles. However, upgrading the materials to something such as steel or ceramic components makes these parts much more durable and long-lasting.
Are bigger brakes needed for bigger rims?
Bigger wheels or rims do not require a brake change, but the heavier wheels do. When there is an increase in rotational mass, this requires more effort to change the direction in which your vehicle is traveling. If you wish to maintain the same level of performance, you will need bigger brakes and more engine power to accommodate the increased weight and mass of larger wheels and rims.
