Rear Brake Pad Wear Sensor for BMW Z4

Standard Ignition PWS275 is a rear disc brake pad wear sensor for select 2009-2010 BMW Z4 applications. It monitors brake pad condition at the brake caliper and helps trigger a warning when pad wear reaches the sensor threshold.

Key Features

  • Disc brake pad wear sensor for rear brake applications
  • Mounts at the brake caliper
  • Female connector with round connector shape
  • 1 connector, 2-pin terminal design
  • Harness length: 51.5 in. (1308.1 mm)
  • Standard Ignition PWS275 replacement sensor

Detailed Description

Built for rear brake wear monitoring, this sensor is specified for 2009-2010 BMW Z4 models and uses a 51.5-inch harness to reach the factory connection point. The female round connector and male pin terminals support a direct-fit electrical connection at the brake caliper. If you are replacing a worn or damaged BMW Z4 rear brake pad wear sensor, Standard Ignition PWS275 provides the correct fitment and connector layout for the listed application. This part cross-references BMW OE number 34356789446 and WS475 for the same application.

What This Sensor Helps Address

  • Brake pad wear warning light staying on
  • Broken or damaged rear pad wear sensor wiring
  • Intermittent brake wear indicator signals
  • Fault codes related to rear brake pad monitoring
  • Loss of brake pad wear alert function on BMW Z4 rear brakes

Installation Notes and Tips

Fits 2009-2010 BMW Z4, rear. Confirm the connector style, harness routing, and caliper mounting point before installation. Inspect the brake pads and rotor condition at the same time, since a worn sensor often indicates the pads have reached service limits. Verify the sensor is seated correctly at the caliper and that the harness is routed away from moving suspension and brake components.

Quality Assurance

Standard Ignition supplies replacement electrical and sensor components for automotive service applications. PWS275 is built to match the listed fitment and connector specifications for the BMW Z4 rear brake wear sensor application.
