    Wilwood 140-2112-BD Details

    FDLI Pro-Series rear disc brake kits provide a complete solution for popular muscle car rear axles on applications where individual wheel parking brake assemblies are not required. Forged billet Dynalite four piston calipers, two-piece hat and rotor assemblies, and high friction pads provide optimized and balanced braking for all types of off-road, competition, and other customized applications. FDLI calipers can be optioned with a full range of finishes to reflect personalized style. Rotor choices provide options for high-tech show winning style, or heavy weight durability and cooling capacity for high heat competition.

    Specs

    Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
