Billet NDL Caliper Radial Mount Side Inlet

The Billet NDL Caliper Radial Mount Side Inlet is a precision-engineered four-piston brake caliper designed for high-performance tactical and law enforcement vehicles requiring reliable stopping power and consistent modulation under demanding field conditions. Built from aluminum and finished in hard gray anodize, this caliper is engineered to handle sustained duty cycles where brake fade tolerance and rapid heat dissipation are non-negotiable. Purpose-built for operators who depend on their vehicles to perform in critical response scenarios, this component delivers the thermal management and mechanical durability expected of professional-grade braking systems.

This four-piston design distributes braking force evenly across a 12.720-inch outer diameter rotor measuring 0.810 inches thick, maximizing contact surface area and reducing brake temperature rise during prolonged deceleration or pursuit scenarios. The radial mount configuration at 4.75 inches allows for precise caliper positioning and alignment with minimal runout, critical for preventing uneven pad wear and maintaining consistent pedal feel. Gray anodized billet aluminum construction provides corrosion resistance while keeping unsprung weight minimal—essential in tactical platforms where every pound impacts handling and fuel efficiency. The side inlet design facilitates smooth brake fluid delivery and supports dual-line systems common in modern law enforcement vehicles.

Ideal for agencies upgrading factory braking systems or aftermarket builders specializing in tactical vehicle platforms, the Billet NDL Caliper Radial Mount Side Inlet pairs seamlessly with cross-drilled or slotted rotors and high-friction pad compounds. Installation requires proper brake line routing and fluid system flushing to eliminate air and ensure sealed operation. Operators should verify caliper-to-wheel clearance during fitment, as performance calipers demand specific hub and rotor combinations. This component is sold individually; complete brake upgrades require matched rotors and pads. Proper brake system maintenance and periodic inspection ensure longevity and peak stopping performance in the field.
