If the car was purchased new, check the owner's manual or with the manufacturer. If it was purchased second hand, a previous owner may have installed different braking system parts.
If the owner's manual is not available, you may be able to download it from the manufacturer's website. You can contact the manufacturer or your dealership as well. If someone else has previously owned the car, some parts of the stock braking system may have been changed. If you cannot contact the previous owners to get this information, you may need to bring the car to a mechanic to verify what parts are installed.
