Front Left Brake Pad Wear Sensor for BMW 7 Series F01 F02 F03 F04

1. OE Identification and Vehicle Fitment

The KU-FV-03-009 is a front-left brake pad wear sensor for compatible BMW 7 Series vehicles using the F01, F02, F03 or F04 chassis. Manufactured as a vehicle-specific replacement, it follows the corresponding cable routing, connector shape and mounting arrangement for direct installation.

• BMW 7 Series F01
• BMW 7 Series F02
• BMW 7 Series F03
• BMW 7 Series F04
• Applicable Years: 2008–2015
• OE Reference: 34356775850
• Formatted OE: 34 35 6 775 850

Fitment should be confirmed using the OE number, VIN, production date and original sensor configuration before ordering.

2. Brake Pad Wear Detection

The sensor monitors the usable thickness of the front brake pad through an integrated contact circuit. When pad wear reaches the sensor contact point, the circuit changes state and activates the corresponding brake-wear warning through the vehicle instrument system.

• Wear Contact Circuit: Detects when the brake pad reaches its service limit.
• Dashboard Warning Signal: Communicates the wear condition to the vehicle warning system.
• Front-Axle Monitoring: Provides wear indication for the corresponding front brake assembly.
• Maintenance Reminder: Helps workshops identify when brake-pad inspection or replacement is required.
• Brake Disc Protection: Timely warning helps reduce the risk of continued driving with excessively worn pads.

3. Cable and Connector Construction

The sensor uses a sealed cable structure designed for installation around the wheel and brake assembly. Its protective outer layer helps withstand temperature changes, road splash, repeated movement and exposure to common underbody contaminants.

• Protective Rubber Jacket: Helps resist heat, cold and repeated cable flexing.
• Sealed Connector: Supports stable electrical contact around the wheel area.
• Road-Splash Resistance: Helps protect the internal conductor from water and dirt.
• Salt and Corrosion Resistance: Supports operation in wet and winter road conditions.
• Vehicle-Specific Retaining Points: Follow the corresponding original cable-routing path.

4. Replacement and Workshop Installation

The molded connector and cable layout support direct connection to the corresponding BMW brake-wear monitoring circuit. No cable cutting or vehicle-body modification is required when replacing a matching sensor.

• Disconnect the vehicle battery when required by the applicable service procedure.
• Compare the new sensor with the original connector and cable routing before installation.
• Route the cable through the original retaining points and keep it clear of rotating components.
• Replace the wear sensor when it has contacted the brake disc or triggered the warning circuit.
• Reset the brake-service indicator according to the vehicle service procedure after installation.

5. Aftermarket Supply Value

The OE-number-based identification and vehicle-specific design support efficient sourcing by brake specialists, repair workshops and automotive-parts distributors. Each unit is supplied individually for front brake service and replacement programs.
