Truck Right Brake Pad Wear Indicator Sensor Replacement for Mercedes-Benz Actros Axor Atego | OEM 9455421918 0005402136 90572

Product Overview The 9455421918 / 0005402136 / 90572 Right Brake Pad Wear Indicator Sensor is a high-sensitivity automotive safety component engineered as a premium aftermarket replacement for Mercedes-Benz commercial heavy trucks and fleet transport logistics vehicles. Installed specifically on the passenger-side (Right) wheel braking caliper assembly, this sensor line closely monitors the residual friction lining thickness of the brake pads. When the pad material wears down to its critical safety thresholds, the sensor completes an electrical warning loop to the central instrument cluster dashboard, prompting timely maintenance to avoid catastrophic rotor damage or braking power degradation. Technical Specifications Primary Mercedes-Benz OE Reference Codes: 9455421918, 0005402136, 9454201318, 9454201618, 9455420118, 9455420318, A9455421918, A0005402136 Other Fleet Cross-References: 9455421618, 9455421318, 9455421018, 90572 Component Type: Heavy-Duty Disc Brake Pad Wear Lead / Right-Hand Brake Warning Sensor Positioning: Front/Rear Right Wheel Axle Calipers Condition: Brand New Premium Aftermarket Replacement Vehicle & System Compatibility This brake lining warning wire features factory-aligned terminal pins and high-temp protective sleeving lengths, offering direct drop-in integration across mainstream Mercedes-Benz heavy commercial chassis platforms: Truck Model & Series Braking Layout & Application Details Mercedes-Benz Actros Series (MP1, MP2, MP3 generations) Fits premium heavy haulage models (e.g., 1840, 1844, 2540, 2641, 3341, 4141 V6/V8 powertrains) running original factory air disc brake configurations. Mercedes-Benz Axor Series (Axor 1 & Axor 2) Widespread integration across medium-to-heavy regional distribution tractors and rigid multi-axle freight chassis requiring standard 9455421918 warning lines. Mercedes-Benz Atego Series Fits corresponding heavy distribution mediums and urban rigid cargo builds equipped with multi-wheel monitoring loops. Performance Benefits Thermal-Insulated Outer Jacket: Wrapped in a premium high-durability sheathing designed to resist scorching brake dust, intense radiant caliper heat, and chemical exposure from road grime. Precise Electrical Linearity: Built with high-purity internal copper wiring to eliminate resistance variations, ensuring zero false alarms or dashboard cluster flickering. OEM-Spec Snap Fitment: Form-fit clips allow the operator to smoothly secure the sensor probe inside the brake pad slot without shaving or using special custom tools. Maintenance Tip: In heavy-duty logistics transport routines, whenever you replace a set of worn brake pads on your Mercedes-Benz Actros or Axor, the wear indicator sensors must always be replaced as well. Once the sensor’s tip grinds against the brake rotor, the circuit is permanently compromised and cannot be reset or spliced. When installing the new 9455421918 sensor wire, ensure it is routed cleanly along the original chassis brake lines and suspension swing arm hooks. Leave adequate slack for wheel turning clearances to prevent the cable from catching road debris or snapping under intense articulation.
