How to Self-Check a Car's Brake System?

[McSamuel]

Brake pads generally have varying replacement intervals depending on driving habits and road conditions. A brake pad typically has a thickness of about 15 millimeters. When the brake pad wears down to approximately 4-5 millimeters, it is recommended to replace it immediately, as this is already the wear limit of the brake pad. More detailed information is as follows: 1. Thinning brake pads: If you continue to use them, the metal indicator on the brake pad base will directly wear against the brake disc, producing a sharp friction sound as a warning. Further wear due to hard friction can easily damage the brake disc. 2. The brake disc is a very important component of the braking system. Even minor issues with your brake disc can affect the safety of the entire vehicle. Although car brake discs are not considered consumables, they are still prone to wear. After a certain mileage of use, brake discs will show wear. If the surface of the brake disc becomes uneven or the thickness falls below the standard, it can severely affect braking performance over time. Generally, it is advisable to inspect the brake disc when replacing the brake pads. If any damage is found, the brake disc should also be replaced to avoid potential safety hazards.
