What does excessive wear of brake pads mean?
2 Answers
Excessive wear of brake pads refers to the brake pad warning, which requires timely inspection and replacement of new brake pads. The following is a detailed introduction to automotive brake pads: 1. Automotive brake pads refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction blocks bear external pressure and generate friction to achieve vehicle deceleration. 2. Automotive brake pads are generally composed of steel plates, bonded heat insulation layers, and friction blocks. The steel plates are coated to prevent rust, and the coating process uses an SMT-4 furnace temperature tracker to detect the temperature distribution during the coating process to ensure quality. The following is a detailed introduction to brake pads: 1. Brake pads refer to the brake pads. When the vehicle prompts excessive wear of the brake pads, it is generally because the brake pads have reached the wear limit and need to be replaced in time. Otherwise, it will cause brake failure and damage to the brake disc. 2. There is also a less common reason that can cause the vehicle to display a warning of excessive wear of the brake pads. When the brake pad wear sensor is damaged and an open circuit occurs, it can cause the vehicle to give a false alarm, and the vehicle dashboard will also prompt excessive wear of the brake pads.
Excessive brake pad wear means the brake pads are worn too severely, almost to their limit, indicating that the pads have become too thin, leading to reduced braking performance and even potential brake failure. This typically occurs after prolonged driving or frequent hard braking, affecting the brake discs and calipers as well. The detection method is simple: when parked, take a look at the brake discs inside the wheels—if the pad thickness is less than 3mm, it's dangerous. Alternatively, if you hear a sharp squealing sound while braking, it's a sign they need replacement. Failing to replace them promptly increases braking distance and raises the risk of accidents. I recommend checking them during every maintenance service—spending a bit on new pads is much cheaper than repairing other components, and safety is priceless. Pay extra attention when driving on mountain roads or in rain or snow, as heavily worn pads have poor grip. Don’t wait for an accident to regret it.
