Caliper FNDL 3.50in Mt 1.75 Piston

The Caliper FNDL 3.50in Mt 1.75 Piston is a heavy-duty four-piston brake caliper engineered for high-performance tactical and off-road applications where stopping power and thermal management are non-negotiable. Designed for operators and enthusiasts who demand reliable braking under demanding conditions, this aluminum caliper delivers the clamping force required for vehicles running larger rotors or operating under sustained load. Built to military and law enforcement standards, it serves as a direct upgrade path for platforms requiring precision hydraulic braking without compromise.

Manufactured with gray anodized aluminum construction, the Caliper FNDL 3.50in Mt 1.75 Piston features four independent pistons that distribute clamping force evenly across the brake pad surface, reducing fade during repeated stops and improving modulation control. The 3.50-inch lug mounting interface ensures secure attachment to standardized brake applications, while the 1.75-inch piston bore is calibrated for optimal pressure delivery across 0.380-inch thick rotors with a 12.720-inch outer diameter. Anodized finish provides corrosion resistance in saltwater, mud, and high-humidity environments—critical for vehicles operating in austere tactical or field conditions. The four-piston design inherently offers superior heat dissipation compared to single or dual-piston units, extending pad life and maintaining consistent braking response during extended operations.

This caliper is ideal for military support vehicles, armored personnel carriers, tactical training rigs, and heavy-duty civilian platforms requiring retrofit or performance brake upgrades. Installation requires compatibility with 3.50-inch lug-mount frameworks and rotors measuring 12.720 inches OD; verify your vehicle's brake specifications before ordering. Operators and technicians familiar with hydraulic brake service will find installation straightforward, though professional installation is recommended to ensure proper pad bedding and bleed procedures. At 3.55 pounds, this unit integrates easily into existing brake systems without requiring structural reinforcement, making it a practical upgrade for legacy platforms or new-build tactical vehicles.
