Note: Some factory specifications may not be included with your Porterfield aftermarket pads, such as provisions for connecting sensor wires and other non-essential clips and holes. These possible omissions will not affect the performance of the brake pads. Inspect brake pads at least every 10,000 miles. Once the brake pad thickness (not including the metal backing plate) is less than 3/16" it is time for new brake pads.
