Wilwood Big Brake Kit Wilwood Big Brake Kit features dynamically-mounted rotors and upgraded calipers your UTV / Side-by-Side. This kit features fixed mount multi-piston calipers with greater clamping force over stock, and larger diameter floating rotors for more brake torque and a harder bite, improving braking on higher-powered UTVs. Built with forged aluminum differential-bore four or six piston calipers reduce deflection and provide more uniform engagement to increase braking force and improve feel so you avoid that squishy pedal. The high-friction steel rotors, are up to 20% greater in diameter and thicker for less distortion and the dynamic mounting reduce thermal stress and prevent piston knockback from rough terrain.
