Ksport BKBM300-435SO DualComp Dual Caliper Big Brake Kit with Caliper - 4-Piston

The Ksport BKBM300-435SO DualComp Big Brake Kit is a complete dual-caliper braking solution engineered for enthusiasts who demand independent foot brake and handbrake performance from a single, compact caliper assembly. This innovative system integrates both braking functions into one streamlined 4-piston caliper unit — 2 pistons dedicated to the hydraulic foot brake and 2 pistons dedicated to the handbrake — with each circuit operating fully independently on its own hydraulic system.

Designed as a true bolt-on upgrade, the Ksport DualComp kit eliminates the complexity of sourcing multiple components by including everything required for a complete installation right out of the box.

Key Features:

• 4-Piston Dual-Function Caliper: Single caliper body houses two independent 2-piston circuits — one for the service (foot) brake and one for the handbrake
• Fully Independent Systems: Foot brake and handbrake circuits operate on separate hydraulic lines for maximum control and reliability
• Floating Brake Disc: High-performance floating rotor design reduces heat transfer and allows for thermal expansion, improving braking consistency
• Complete Bolt-On Kit: No fabrication required — designed for direct installation with all necessary hardware included
• Includes Everything Needed: Calipers, floating brake disc, performance brake pads, and all required installation hardware

The Ksport DualComp Big Brake Kit is the ideal upgrade for performance driving, motorsport, and drift applications where a reliable, high-performance handbrake integrated with the rear service brakes is essential. Ksport's engineering ensures consistent, fade-resistant stopping power with the convenience of a single-caliper, dual-function design.
