Big Brake Kit – the ultimate braking system upgrade

A Big Brake Kit (BBK) is a comprehensive brake system upgrade and one of the most effective performance improvements you can make to your car. It typically includes larger brake discs, multi-piston calipers, high-performance brake pads, and upgraded brake lines and fluid, all designed to deliver stronger braking power and improved resistance to overheating during intense driving.

Benefits of a Big Brake Kit

  • Increased braking force:
    Larger discs and 4-piston calipers provide better pad-to-disc contact and more even pressure distribution, resulting in stronger and more consistent braking, even under extreme conditions.
  • Improved heat dissipation:
    Bigger, ventilated, and slotted discs, combined with high-grade materials, help prevent overheating, allowing for repeated hard braking without a loss in performance (known as fading).
  • Durability and reliability:
    High-quality caliper construction minimizes deformation, while advanced pad and disc materials extend the system’s lifespan.
  • Better brake modulation and control:
    Multiple pistons and precise system geometry give the driver more accurate control of braking force, improving both safety and driving comfort.

When is it worth investing in a BBK?

A Big Brake Kit is especially recommended for tuned or high-performance vehicles, as well as cars used for spirited driving or track days, where factory brakes often reach their limits under heavy load.

It’s also an excellent choice for drivers who prioritize safety, precision, and reliability in every situation.


Upgrading to a Big Brake Kit is one of the most valuable investments you can make for your car’s safety and performance.
It enhances braking efficiency, heat resistance, and overall durability, while giving you a more responsive and confident brake feel.
