The wear degree of the car brake pads is directly related to driving safety, so it is very important to understand to what extent the wear of the car brake pads will endanger driving safety.1. Structure and function of car brake padsCar brake pads are one of the key components in the automobile braking system. They are usually installed in the brake caliper and rub against the brake disc to slow down or stop the vehicle.Car brake pads are usually composed of friction materials, backing plates and alarms. The friction material is responsible for generating friction, the backing plate provides structural support, and the alarm is used to indicate wear.2. Safe thickness of car brake padsSafe thickness recommended by manufacturers: The safe thickness of car brake pads may vary for each model and brand. Generally speaking, the thickness of new car brake pads is about 12-15 mm, and manufacturers usually recommend that car brake pads be replaced when the thickness is less than 3-4 mm.Minimum safety thickness: In some areas with stricter regulations, the minimum safety thickness of Car Brake Pads may be lower, usually around 2 mm. However, when worn to this extent, the performance of Car Brake Pads has been significantly reduced, the braking distance will be significantly increased, and the braking efficiency will be greatly reduced.3. Detection method of Car Brake Pads wearVisual inspection: Regularly checking the thickness of Car Brake Pads is the most direct method. You can use a dedicated Car Brake Pads thickness gauge to measure, or directly observe the distance between the Car Brake Pads and the backing plate.Alarm: Many modern cars are equipped with electronic or mechanical Car Brake Pads wear alarms. When the Car Brake Pads are worn close to the minimum safety thickness, the alarm will sound or light up the indicator to remind the driver that the Car Brake Pads need to be replaced.Feeling: If the brake pedal feels "soft" when braking or the braking distance is significantly increased, this may be a sign of excessive wear of the Car Brake Pads.4. Harm of excessive wear to driving safetyIncreased braking distance: Car Brake Pads with excessive wear will significantly increase the braking distance, especially in emergency braking, which may lead to failure to stop in time.Reduced braking efficiency: Car Brake Pads with excessive wear are prone to lose friction at high temperatures, resulting in reduced braking efficiency and even brake failure.Damaged brake disc: When the Car Brake Pads are excessively worn, the back plate may directly contact the brake disc, causing scratches or deformation on the surface of the brake disc, further affecting the braking performance.5. RecommendationsRegular inspection: It is recommended to check the Car Brake Pads every six months or every 10,000 kilometers, especially after long-distance driving or heavy-load driving.Timely replacement: Once the thickness of the Car Brake Pads is found to be close to or below the minimum safety thickness recommended by the manufacturer, it should be replaced immediately to avoid potential safety risks.When the Car Brake Pads are worn to a thickness close to or below the minimum safety thickness recommended by the manufacturer, it will significantly affect driving safety. It is recommended that drivers check the thickness of the Car Brake Pads regularly and replace them in time according to actual conditions to ensure the normal operation of the brake system.
