Power Stop LLC warrants its rotors and pads to be free from defects in materials or workmanship for 90 days from the purchase date or 3,000 miles of use, whichever occurs first. The product, when properly installed in the type of vehicle prescribed, and in which a material or workmanship defect is found, will be exchanged free of charge if returned to the seller who is authorized to service this warranty. Power Stop LLC is not responsible for its products when they are subjected to misuse, abuse, improper application, improper installation, or accident. This 90-day/3,000-mile warranty excludes failure of components due to disc thickness variation (DTV*), usually indicated by brake pulsation. Normal wear is not covered by this warranty.
