Product Details

The Ksport BKBM030-435SO DualComp Big Brake Kit is an all-in-one dual caliper braking solution engineered for drivers who demand independent foot brake and handbrake performance from a single compact unit. Unlike conventional big brake kits, Ksport's innovative DualComp system integrates a single 4-piston caliper — with 2 pistons dedicated to the foot brake circuit and 2 pistons dedicated to the handbrake circuit — each operating independently on its own hydraulic system.

This complete bolt-on kit is designed for straightforward installation and includes every component needed to upgrade your braking system right out of the box.

Key Features:

  • Dual-circuit 4-piston caliper — 2 pistons for foot brake, 2 pistons for handbrake, fully independent operation
  • Floating brake disc — reduces heat transfer and minimizes disc warping under aggressive use
  • High-performance brake pads included for immediate use
  • Complete hardware kit included for a true bolt-on installation
  • Engineered as an integrated dual caliper system — eliminates the need for a separate handbrake caliper
  • Designed for performance driving, motorsport, and demanding street applications

What's Included:

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

The Ksport DualComp Big Brake Kit delivers a clean, professional-grade upgrade for enthusiasts seeking reliable, high-performance braking with both foot and handbrake functionality in one streamlined package.

Order was received promptly

Fast and easy ordering and delivery

Yeah I think I did good but some happened there you sent me an envelope that was 10 times the size of my package I guess that's why you charge me 7:50 for the shipping and I'm wondering was it too much because it cost $7.01 when I went back online and was looking for it I wonder if you gave me the wrong price for Black Friday
