Detailed Description

What It Helps Address

  • Broken or damaged front right wear sensor lead
  • Fault codes related to the pad wear monitoring circuit
  • Loss of continuity at the brake caliper sensor connection
  • Service replacement after brake pad wear sensor damage

Installation Notes and Tips

Install at the brake caliper and route the 12.75-inch harness to match the original path. Confirm connector style, terminal type, and front right position before installation. Verify vehicle application by model year and rotor type, since some Porsche Boxster, Cayman, and 911 listings require steel rotors.
