What is the standard thickness of new brake discs?

[SabrinaAnn]

New brake discs typically have a standard thickness of around 15 centimeters. Brake pads need to be replaced when their thickness falls below 2 millimeters. Precautions for using brake pads: 1. They must be replaced when worn to the limit position, otherwise braking effectiveness will decrease. Brake pads are consumables that gradually wear out during use, which could even lead to safety incidents; 2. Inspect the brake pads every 5,000 kilometers driven, checking not only the remaining thickness but also the wear condition of the pads; 3. Check whether the wear on both sides is similar and whether the retraction is smooth. If any abnormalities are found, immediate replacement is necessary.
