PowerStop SW-1527 Disc Brake Pad Wear Sensor - Rear

Rear Euro-Stop Brake Wear Sensor

PowerStop SW-1527 is a rear disc brake pad wear sensor built for Euro-Stop applications that use electronic pad wear monitoring. It is designed to match OEM form, fit, and function while handling the heat and electrical demands of everyday braking. For Porsche Boxster and Porsche Cayman rear brake service, this sensor helps restore proper wear-indicator operation after pad replacement.

Key Features

• Rear disc brake pad wear sensor for electronic brake wear monitoring
• OEM-style form, fit, and function for direct replacement use
• Built to withstand extreme temperatures for stable electrode conductivity
• White connector with oval shape, 2-wire layout, and 2 terminals
• Includes a grommet and uses a male connector with female terminals
• Wiring harness length: 20.07 in. / 510 mm
• PowerStop SW-1527 is listed for rear fitment on Porsche Boxster and Porsche Cayman applications

Product Details

PowerStop’s Euro-Stop brake wear sensor line focuses on replacing worn electronic sensors at the same time as brake pads and rotors. The SW-1527 is engineered for rear axle use and follows the original sensor layout used on select Porsche models. If you are servicing a Porsche Boxster rear brake system or a Porsche Cayman rear brake system, this part number helps maintain the brake wear warning circuit after maintenance. This part cross-references Centric Parts 116.37027 for the same application.

What It Helps Address

• Brake wear warning light staying on after pad service
• Damaged or worn rear brake pad wear sensor wiring
• Faulty sensor readings from heat-affected brake components
• Loss of electronic pad wear monitoring on rear brakes
• Need for an OE-style replacement sensor during brake maintenance

Installation Notes

Install on the rear brake position only and verify connector shape, terminal style, and harness routing before final assembly. Replace the sensor when the original wear indicator is damaged, triggered, or no longer reads correctly. Confirm vehicle-specific fitment for your Porsche Boxster or Porsche Cayman by year and brake package before ordering. Part number SW-1527 should be matched to the rear Euro-Stop electronic wear sensor application shown in the fitment data.

Quality Assurance

PowerStop builds this sensor to meet or exceed OEM requirements for form, fit, and function. The design is intended to provide consistent conductivity and long-term operation under brake heat exposure, supporting reliable wear-indicator performance over extended mileage.
