Dynamic Friction Company Disc Brake Pad Set P/N:1551-2191-00
If you're shopping for 2019-2025 Infiniti QX50 brake pads, the DFC 4000 HybriDynamic rear disc brake pad set, part number 4000-2191-00, is a direct-fit replacement for the listed applications: the 2019-2025 Infiniti QX50 and the 2022-2025 Infiniti QX55. It is designed to give a consistent pedal feel and responsive, low-noise stops at the rear axle.
Dynamic Friction Company's HybriDynamic formulation aims to take the guesswork out of choosing a brake pad material. It combines a steady pedal and strong brake response with low dust and low noise, which suits daily driving. Engine details for each application are listed in the "Vehicles it fits" section.
Signs your rear pads may need replacing include squealing or grinding when braking, longer stopping distances, or pads worn thin at inspection. For even, balanced braking, replace the pads on both sides of the rear axle at the same time.
