Product Details

The Ksport BKBM040-435SO DualComp Big Brake Kit is an all-in-one dual-function brake upgrade engineered for enthusiasts who demand both powerful foot braking and a dedicated handbrake from a single, compact caliper assembly. Ksport's innovative DualComp system features a single 4-piston caliper with two pistons dedicated to the foot brake circuit and two pistons dedicated to the handbrake circuit — each operating independently on its own hydraulic system for precise, reliable performance.

Key Features:

  • Dual-circuit 4-piston caliper — 2 pistons for foot brake, 2 pistons for handbrake, fully independent operation
  • Floating brake disc included for improved heat dissipation and reduced brake fade
  • Complete bolt-on kit — includes everything needed for a straightforward installation
  • High-performance brake pads included and ready to install
  • All required mounting hardware included for a clean, professional fit
  • Designed for performance driving, motorsport, and drift applications requiring an integrated e-brake solution

What's Included:

  • 4-Piston DualComp Caliper(s)
  • Floating Brake Disc(s)
  • Brake Pads
  • All required installation hardware

The Ksport DualComp Big Brake Kit eliminates the need for a separate dedicated handbrake caliper, streamlining the braking setup while delivering competition-grade stopping power. Whether used on the track or the street, this kit provides a clean, professional-grade brake system upgrade in one complete package.
