Product Details

The Raybestos R-Line EWS139 is built for rear brake pad wear monitoring on BMW 528i, 535i, 550i, ActiveHybrid 5, and 640i/650i models across multiple model years. The R-Line product line covers replacement brake components for everyday service work, and this sensor follows the OE-style layout needed for proper fitment at the rear brake assembly. If you are replacing a worn or damaged BMW rear brake wear sensor, EWS139 provides the correct connector style, terminal layout, and harness configuration for the listed applications.

Compatible With BMW 528i rear, BMW 535i rear, BMW 550i rear, BMW ActiveHybrid 5 rear, BMW 640i Gran Coupe rear, BMW 650i Gran Coupe rear, and related xDrive variants listed below. Raybestos EWS139 is also a direct search match for technicians and parts buyers looking for a rear brake pad wear sensor for BMW 640i xDrive Gran Coupe, 650i xDrive, or 535d xDrive rear applications.

What It Helps Address

  • Brake wear warning light triggered by a damaged rear sensor
  • Broken or frayed sensor wiring at the rear brake assembly
  • Connector mismatch during rear brake service
  • Faulty pad wear signal after brake pad replacement
  • Loss of brake pad wear monitoring on supported BMW models

Installation Notes

Install at the rear brake position only. Verify connector style, terminal count, and harness routing before installation. The sensor uses a female connector, male terminals, and integrated grommets for routing through the brake assembly. Confirm vehicle-specific fitment by year, model, and rear position before ordering.
