Genuine BMW 34 35 8 832 142 Disc Brake Pad Wear Sensor - 34 35 8 832 142

The Genuine BMW 34 35 8 832 142 Disc Brake Pad Wear Sensor is an OEM-direct replacement component engineered to monitor brake pad thickness and alert the driver before pads reach a critically low level. This is a single-use, factory-original sensor sourced directly from BMW.

BMW's brake pad wear sensors are a key part of the vehicle's safety monitoring system. When the pad wears down to its minimum thickness, the sensor contacts the rotor, triggering a warning on the instrument cluster that prompts timely service. Modern BMW models use a two-stage resistance system: an initial yellow advisory warning at 270 ohms, followed by an urgent red dashboard alert once the circuit fully breaks at pad minimum thickness.

Key Features:

• 100% Genuine OEM BMW part — identical to factory-installed hardware
• Two-stage electronic wear detection for early and critical threshold alerts
• Direct plug-and-play connector for straightforward installation
• Single-use component — must be replaced every time brake pads are serviced
• Compatible with BMW's Condition Based Service (CBS) monitoring system
• Backed by BMW's 2-year warranty on Genuine Original Parts

Important: This sensor is a one-time-use part and cannot be reused or reinstalled once removed. Heat and road debris cause the sensor to bond to the brake pad over time. Always replace the wear sensor whenever brake pads are changed to ensure accurate system monitoring and maintain CBS reset compatibility.
