Dynamic Friction Company Disc Brake Pad Set P/N:4000-2191-00

Confident, low-dust stops for daily driving — the Dynamic Friction Company 4000 HybriDynamic Disc Brake Pad Set (P/N 4000-2191-00, also written 4000219100) is a rear-axle brake pad set that drops in as a direct-fit replacement for the 2019-2025 INFINITI QX50 and 2022-2025 INFINITI QX55 (see the Buyer's Guide tab for engine-level fitment). Its HybriDynamic friction formulation is designed to deliver a consistent pedal feel and strong brake response, taking the guesswork out of choosing the right pad material.

• Clean, quiet formula: 100% asbestos-free and copper-free, engineered for low dust and low noise on everyday commutes.
• Stable friction: designed to hold friction performance across a wide temperature range for reliable stopping power.
• Rotor-friendly: built for extended pad life with reduced impact on the rotors.
• Smooth operation: engineered to reduce noise and vibration for a quieter ride.

Brake pads wear as a normal service item; signs the rear pads may need replacing include squealing, reduced braking response, or a lengthening pedal. This listing is one rear-axle set — because pads wear together, replacing both sides at the same time is recommended for even, balanced braking. Always confirm fitment for your specific vehicle before ordering.
