Caliper FNDL 3.50in Mt. 1.38in Piston 1.00in Rtr

The Wilwood Caliper FNDL 3.50in Mt. 1.38in Piston 1.00in Rtr is a professional-grade four-piston brake caliper designed for high-performance vehicles and tactical applications requiring reliable stopping power under demanding conditions. Built by Wilwood, a trusted manufacturer in motorsports and emergency vehicle braking systems, this aluminum brake caliper delivers consistent performance for operators who demand precision and durability in their vehicle's brake system. Whether integrated into a law enforcement pursuit vehicle, military transport, or extreme-duty tactical platform, this caliper provides the thermal management and responsiveness essential for mission-critical operations.

The Dynalite four-piston architecture distributes clamping force evenly across a 1.000-inch-thick rotor, reducing heat buildup and brake fade during sustained braking events—a critical feature for vehicles executing repeated high-speed maneuvers or operating in extreme-temperature environments. Gray anodized aluminum construction provides corrosion resistance and extended service life, while the 3.500-inch lug mount accommodates standard wheel hub configurations found on modern tactical and performance vehicles. The 1.38-inch piston diameter is engineered to balance initial brake feel with stopping authority, ensuring responsive modulation whether executing precision emergency stops or sustained descent braking during mountain operations.

Law enforcement mobile units, military transport platforms, and specialty tactical vehicles benefit most from this caliper's ability to maintain consistent braking performance across repeated duty cycles without performance degradation. Installation requires compatibility with a 12.720-inch outer diameter rotor (1.000-inch thickness) and standard 3.500-inch lug-mount hub geometry. Operators should verify rotor specifications and brake line pressure ratings before installation to ensure optimal performance and system longevity. At 3.99 pounds per unit, this caliper integrates seamlessly into weight-critical platform builds without compromising structural integrity or brake response times.
