DualComp 4-Piston Big Brake Kit

The Ksport BKNS190-444SO DualComp Big Brake Kit is an innovative all-in-one dual-caliper braking solution engineered for performance vehicles that require both a high-performance foot brake and a dedicated handbrake within a single, compact unit. At its core is Ksport's unique 4-piston caliper design, specifically engineered so that two pistons are dedicated to the hydraulic foot brake circuit and the other two are dedicated to the handbrake circuit. These two systems operate completely independently on their own hydraulic systems, delivering precise and reliable control suitable for both daily street driving and demanding motorsport applications. The caliper itself is constructed from aluminum and comes in a vibrant orange finish, housing 4 pistons with a caliper inlet port diameter of M10 x 1. The included brake disc rotors are 356mm (14 inches) in diameter, vented, and feature a slotted surface type. For enhanced performance and reliability, ceramic brake pads are included, although pad shims are not. The system also includes mounting brackets and caliper slides, ensuring a complete bolt-on experience with no additional parts required. The DualComp Big Brake Kit is designed as a rear-position upgrade. Key specifications include a rotor diameter of 14 inches and a rotor width of 32mm. The kit is intended for performance-grade applications and is not subject to CARB regulations. Ksport guarantees the fitment of this kit, which comes with a mounting bracket and anti-rattle springs for a secure installation.
