Overview

The Ksport BKAU072-434SO DualComp Big Brake Kit is a complete braking upgrade designed for enhanced stopping power and precision control. It features a revolutionary all-in-one dual caliper braking solution that provides independent foot brake and handbrake performance from a single, compact unit.

This kit utilizes an innovative DualComp system with a single 4-piston caliper that has a unique split-function design. Two pistons are dedicated to the foot brake circuit, while the other two operate the handbrake circuit. Each circuit functions independently on its own hydraulic system, eliminating the need for a separate handbrake caliper and simplifying installation. The kit includes floating brake discs, high-performance ceramic brake pads, and all required hardware for a straightforward bolt-on installation.

The Ksport BKAU072-434SO DualComp Big Brake Kit delivers a revolutionary all-in-one dual caliper braking solution engineered for drivers who demand independent foot brake and handbrake performance from a single, compact unit. Ksport's innovative DualComp system features a single 4-piston (4-POT) caliper with a unique split-function design. Two pistons are dedicated exclusively to the foot brake circuit, while the remaining two pistons operate the handbrake circuit. Each circuit functions fully independently on its own hydraulic system, eliminating the need for a separate handbrake caliper and simplifying installation without sacrificing performance. Key features include a 4-piston (4-POT) single caliper design with two pistons for the foot brake and two for the handbrake, each on independent hydraulic circuits. As a complete bolt-on kit, it includes high-performance ceramic brake pads and all required hardware for a straightforward installation, with no additional brackets or fasteners needing to be sourced. This kit is ideal for motorsport applications, drift builds, and performance street vehicles where a reliable, integrated foot brake and handbrake solution is essential. The 330mm (13-inch) diameter, vented, and slotted rotors, paired with the aluminum 4-piston calipers, provide a significant improvement over factory braking components.
