When did the car change its brake pads for the first time?
The newly replaced brake pads are hot and sticky, which may be due to poor heat dissipation of the brake pads, failure of the return function of the brake pump, incorrect installation of the brake pads and poor quality of the brake pads. The newly delivered brake pads usually have a running in period, and the contact area between the brake pads and the brake disc is increased through running in.So as to increase the braking force and torque. After running in for a period of time, you can feel that the brake is stable, but the brake generally does not have the smell of burning. If you do not step on the brake for a long time, the brake has the smell of burning, which is mostly caused by poor brake return or incorrect installation of brake pads. If this situation occurs, it needs to be checked in time.
If the brake system fails, the brake pad will rub against the brake disc. Over time, the brake disc will be hot or even burnt. First, check whether the main harness of the engine is burnt, especially on the exhaust side. If there is a burnt smell, the owner needs to repair and replace it immediately. If it is the smell from the clutch friction pad, there is no need to worry, and the impact is small.
During the inspection, we must carefully verify to avoid short circuit caused by careless inspection. The brake pad is a consumable. The brake pad will become thinner after use for a period of time, resulting in the decline of vehicle braking performance. Therefore, the brake pad needs to be replaced in time. Therefore, the vehicle should often check the wear degree of the brake pad. If it is found that the wear is serious, it should be replaced immediately, so as to give better play to the braking performance and improve driving safety.
