{"product_id":"4-piston-hydraulic-handbrake-caliper-kit","title":"4-Piston Hydraulic Handbrake Caliper Kit","description":"The Ksport DualComp Big Brake Kit (BKMZ100-434CO) 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. Designed as a true bolt-on upgrade, this big brake kit delivers serious stopping power without complex custom fabrication.\n\nAt the heart of this kit is Ksport's innovative 4-piston caliper design, which divides its four pistons across two independent hydraulic circuits. Two pistons are dedicated exclusively to the foot brake system, while the remaining two pistons serve the hydraulic handbrake system. Each circuit operates completely independently, ensuring consistent, reliable performance from both braking inputs — a critical advantage for performance driving, drifting, and motorsport applications.\n\nThe complete kit includes a 4-piston dual-circuit caliper, a floating brake disc designed to reduce heat buildup and minimize brake fade, performance brake pads matched to the caliper, and all required hardware, brackets, and bolts for a complete bolt-on fitment. Key features include dedicated 2-piston circuits for each brake function, a floating rotor for improved heat dissipation and consistent pedal feel, and a design that makes it ideal for performance driving, competitive motorsport, and drift applications.\n\nThis purpose-built solution is for enthusiasts who require a clean, reliable, and high-performance dual-caliper setup without the complexity of running two separate calipers and mounting brackets. The caliper pistons are made of aluminum, and the rotors are 13 inches in diameter and feature a vented, drilled surface. The kit is finished in an orange caliper color.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868606755128,"sku":"BKMZ100-434CO","price":2907.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687993908.jpg?v=1787915492","url":"https:\/\/store.motormia.co\/products\/4-piston-hydraulic-handbrake-caliper-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
