How do I know when to replace brake pads?

Replace when pad thickness reaches 3mm or less, or when you hear squealing (wear indicator), grinding, or notice reduced braking performance. Compatible vehicles include 2016-2019 Cadillac ATS, CTS and more.

What's the difference between ceramic and semi-metallic pads?

Ceramic pads run quieter and produce less dust but cost more. Semi-metallic pads offer better heat dissipation for heavy-duty use. Both provide reliable stopping power for daily driving.

What vehicles does this Disc Brake Pad Set fit?

This GM Genuine Parts Disc Brake Pad Set (rear) (Part #171-1158) fits specific vehicle applications. Compatible vehicles include 2016-2019 Cadillac ATS, CTS and more. Use the compatibility checker above to verify fitment for your exact vehicle including engine and trim options.

Is this part covered by warranty?

Yes, this GM Genuine Parts Disc Brake Pad Set includes a 24-month limited warranty covering defects in materials and workmanship. AutoBuffy also offers 30-day hassle-free returns if the part doesn't fit your vehicle.

How fast is shipping?
