Product Details

The R1 Optimum OE Pads line is positioned as an OE-style brake pad solution for drivers who want a direct replacement format for factory rear brake service. For Porsche Cayenne rear brake maintenance, 2551-2166-00 provides a fitment-specific option for the 2019-2020 and 2022-2023 model years.

  • Brake squeal from worn pad material
  • Reduced braking response from thin pads
  • Brake warning service intervals on Porsche Cayenne rear brakes
  • Uneven rear pad replacement needs during brake service

Installation Notes

Verify rear fitment by model year before ordering. For listed Porsche Cayenne applications, confirm that BPS-02042 sensors are required and replace both sensors as specified for the vehicle. Inspect rotors, caliper condition, and pad contact surfaces during installation. Part number 2551-2166-00 should be matched to the rear axle only.
