Caliper FDL 1.38in Bore .380in Rotor

The Caliper FDL 1.38in Bore .380in Rotor by WILWOOD is a fixed-disc light brake caliper engineered for high-performance automotive applications where weight savings and thermal management are priorities. This component is designed for vehicle builders and enthusiasts who demand precision braking on dedicated track builds, street performance cars, and motorsport platforms. The FDL designation indicates a fixed-disc, light-weight design that reduces unsprung mass while maintaining the stopping power required for controlled deceleration in demanding driving scenarios.

With a 1.38-inch bore and compatibility with .380-inch rotors, this caliper delivers efficient hydraulic pressure conversion to friction force, allowing you to fine-tune braking balance and modulation for your specific setup. The fixed-mount design eliminates floating caliper play and compliance, translating pedal input directly into consistent pad pressure. WILWOOD's engineering focuses on durability and heat dissipation, critical factors when running extended track sessions or high-speed highway driving where fade resistance becomes essential. The lightweight construction—just 3.35 pounds—helps minimize brake system weight, improving acceleration response and reducing suspension loads during hard cornering.

This caliper is ideal for builders upgrading vehicles with custom suspension geometry, larger displacement engines, or increased power output that demands superior stopping capability. Installation requires proper rotor sizing at .380 inches and brake line plumbing compatible with your hydraulic system layout. You'll benefit most from this component when paired with stainless steel brake lines, performance-grade fluid, and matched pad compounds rated for your intended use—whether road racing, autocross, or spirited street driving. Verify mounting bracket compatibility with your vehicle's existing front-end geometry before purchase to ensure seamless integration.
