DualComp 4-Piston Rear Big Brake Kit

The Ksport BKNS150-435CO DualComp Big Brake Kit is a complete dual-caliper braking solution designed for vehicles demanding independent foot brake and handbrake performance from a single, compact caliper assembly. This big brake kit offers a true bolt-on upgrade, delivering substantial improvements in braking force, modulation, and control compared to stock brake setups. The unique DualComp system utilizes a 4-piston caliper with a split-circuit design. Two pistons are dedicated exclusively to the foot brake circuit, while the remaining two pistons operate the handbrake circuit. Each circuit functions independently on its own hydraulic system, ensuring precise, consistent actuation for both street driving and motorsport applications. Key features of this kit include a 4-piston dual-circuit caliper, a floating brake disc designed to reduce heat transfer and thermal distortion, and high-performance ceramic brake pads for optimal initial performance. With its 13-inch drilled and vented floating rotors and orange aluminum calipers, this rear big brake kit is ideal for performance and competition vehicles that require a reliable, high-clamping handbrake system integrated into a single caliper unit. Note that pad shims are not included.
