{"product_id":"single-4-piston-caliper-with-independent-handbrake-system","title":"Single 4-Piston Caliper with Independent Handbrake System","description":"This kit features a unique dual-function caliper design that integrates both the foot brake and handbrake into a single, compact 4-piston caliper unit, eliminating the need for a separate handbrake caliper. The DualComp system utilizes a single 4-pot caliper where two pistons operate the foot brake circuit and two pistons operate the handbrake circuit, ensuring precise and reliable braking performance for both street and competition use. This big brake kit is Formula Drift legal.\n\nThe kit boasts a two-piece floating rotor design with 13-inch (330mm) cross-drilled floating brake discs, ideal for street and light track use as they run cooler than slotted rotors. The center hat is crafted from 6061-T6 aircraft-grade aluminum to reduce rotational mass and improve brake response, while also acting as a heat sink. The outer rotor ring expands and contracts independently from the center hat, significantly reducing the risk of heat-induced warping.\n\nKey caliper and hardware features include the single 4-piston caliper with its dual-circuit design, a polished titanium handbrake cylinder and lever for improved feel and precision, and CNC-machined carbon steel caliper brackets for direct bolt-on fitment to OEM bracket locations. The kit also includes D.O.T. compliant stainless-steel braided brake lines. The standard kit includes forged, monoblock aluminum calipers, lightweight two-piece rotors (slotted or drilled), SC5 Street Brake Pads, stainless steel brake lines, all required mounting components and hardware, and an owner's manual.\n\nThis Ksport DualComp big brake system is designed as a true bolt-on upgrade, requiring minimal tools and no permanent vehicle modifications in most applications. It offers fade-free performance on both the street and track and is backed by Ksport's 12-month manufacturer defect warranty. The kit is designed for the Nissan Silvia S15, model years 1999-2002.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868670488888,"sku":"BKNS230-435CO","price":2743.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687991180.jpg?v=1787915739","url":"https:\/\/store.motormia.co\/products\/single-4-piston-caliper-with-independent-handbrake-system","provider":"MOTORMIA","version":"1.0","type":"link"}
