When it comes to enhancing the braking performance of your vehicle, big brake kits are a tempting upgrade for performance enthusiasts. These kits promise larger rotors, multi-piston calipers, and improved stopping power. But are they worth the investment, and how do you choose and install them correctly? In this two-part guide, we’ll delve into the world of big brake kits, exploring their benefits, considerations, and installation steps.

Understanding Big Brake Kits

Big brake kits, often referred to as BBKs, are aftermarket brake upgrades designed to provide superior stopping power and heat dissipation compared to stock braking systems. They typically include larger brake rotors, multi-piston calipers, high-performance brake pads, and stainless steel brake lines.

Benefits of Big Brake Kits

  1. Enhanced Stopping Power: BBKs offer increased brake leverage and surface area, resulting in shorter stopping distances, especially during high-speed driving.
  2. Improved Heat Dissipation: The larger rotors and multi-piston calipers are better equipped to manage heat, reducing the risk of brake fade during aggressive driving or track use.
  3. Reduced Brake Wear: BBKs distribute braking force more evenly, which can lead to less wear and tear on brake pads and rotors.
  4. Aesthetic Appeal: Upgraded calipers and rotors can add a sporty and eye-catching look to your vehicle.

Considerations Before Installing a Big Brake Kit

  1. Wheel Clearance: Ensure that your wheels have adequate clearance for the larger calipers and rotors included in the BBK.
  2. Master Cylinder Compatibility: Check if your vehicle’s master cylinder is compatible with the increased brake fluid demand of a BBK.
  3. Driving Style: BBKs are most beneficial for aggressive driving, track use, or heavy vehicles. Consider your driving habits before investing.
  4. Budget: Big brake kits can be costly, so weigh the cost-benefit ratio carefully.

Choosing the Right Big Brake Kit

Selecting the appropriate BBK for your vehicle involves several considerations:

1. Vehicle Compatibility

Ensure that the BBK you choose is compatible with your vehicle’s make, model, and year. Manufacturers often provide compatibility charts or support to help you make the right choice.

2. Rotor Size

BBKs come with various rotor sizes. Larger rotors offer improved heat dissipation and braking performance but may require larger wheels for clearance. Consider your wheel size and driving needs.

3. Caliper Type

BBKs feature different caliper types, such as fixed and floating. Fixed calipers provide consistent performance, while floating calipers are more budget-friendly. Choose based on your driving style and budget.

4. Brake Pads

BBKs often include high-performance brake pads. Consider the type of driving you do, as some pads are optimized for street use, while others are designed for track performance.

Installing a Big Brake Kit

Installation of a BBK involves several steps:

1. Gather Tools and Supplies

Collect the necessary tools, including a hydraulic jack, jack stands, brake fluid, and a torque wrench. Read the BBK manufacturer’s instructions carefully.

2. Lift the Vehicle

Safely lift the vehicle and secure it with jack stands. Remove the wheels to access the stock braking components.

3. Remove Stock Components

Follow the manufacturer’s instructions to remove the stock calipers, rotors, and brake lines. Be cautious when disconnecting brake lines to avoid fluid leakage.

4. Install the BBK Components

Install the new rotors, calipers, and brake lines according to the manufacturer’s specifications. Torque all bolts to the recommended values.

5. Bleed the Brakes

Properly bleed the brake system to remove air bubbles and ensure brake fluid circulation. Use the recommended brake fluid type.

6. Test and Bed-In

After installation, perform a brake test in a safe area to ensure proper function. Follow the manufacturer’s bed-in procedure for the brake pads.

7. Verify Wheel Clearance

Check that the wheels clear the new calipers and rotors. If needed, consider wheel spacers or different wheels.


Big brake kits can significantly enhance your vehicle’s braking performance, making them a valuable upgrade for performance enthusiasts. However, the decision to install a BBK should be based on your driving style, vehicle compatibility, and budget. When chosen and installed correctly, a BBK can transform your driving experience, providing improved stopping power and greater control.

Always follow the manufacturer’s instructions for the specific BBK you choose, and consider seeking professional help if you’re unsure about the installation process. Elevate your vehicle’s braking performance and enjoy the benefits of big brake kits tailored to your needs
