Teach you three strokes self-test brake pads whether the replacement thickness easy to judge

Method 1: Look at the thickness
        A new brake pad thickness is generally around 1.5cm, with the use of continuous friction will gradually thinning the thickness. Professional technical staff suggested that when the naked eye to observe the thickness of the brake has been the original thickness of about 1/3 (about 0.5cm) or so, the owner will increase the frequency of self-test, ready to replace. Of course, individual models due to wheel design reasons, do not have the conditions to see the naked eye, you need to remove the tire to complete.
        Each brake pad has a protrusion on both sides of the mark, the thickness of the logo in about two or three millimeters, which is the brakes the thinnest replacement limit, if the brake plate thickness has been parallel with this mark, you must change. So when the thickness of the brake pads close to this mark when the owner will be ready to observe the preparation, but in the case of non-demolition of the tire through the naked eye is difficult to accurately observe the current number of models in the brake pads are too thin when the instrument hand brake light position Prompt, relative to the self-test to facilitate some.
       Small recommendations: brake pads according to the car environment and driving habits without strict replacement intervals, generally about 60,000 km driving to consider replacement. When the naked eye observation brake thinner should be required in the maintenance of technical staff to check, because the naked eye observation will be there will be errors, professional service stations through the caliper than the naked eye observation more rigorous.
Method 2: Listen to the sound
       If the brake is accompanied by a slight "iron rub iron" (also may be the brake pad at the beginning of the installation of the role of running), then the brake pads must be replaced immediately. Because the brakes on both sides of the limit logo has been directly friction brake discs, that brake pads have exceeded the limit. In this case, in the replacement of the brake pads at the same time to meet the brake disc check, there is often the sound of the brake disc has been damaged, this time even if the replacement of the new brake pads still can not eliminate the sound, serious need to replace the brake disc The
       In addition, some bad quality of the brake pads in a hard spot, this will produce abnormal sound, the general situation of such abnormalities will be worn out after a period of time to disappear.
       Small advice: When you hear the sound of the brake is often late, when the brake disc more or less will be damaged. Brake disc prices are much higher than the brake pads, so it is recommended that you check the brake pads, to avoid damage to the brake disc thing.
Method 3: Feeling the intensity
       If the brake is very difficult, it is possible that the basic friction has been lost friction, and this time must be replaced, otherwise it will lead to serious accidents.
       Small advice: This method is relatively abstract, with the feeling may be some bad to grasp, so to develop a good self-test habits is very important. In addition, the brake effect will reduce the brake oil consumption will increase, so replace the brake pads at the same time to focus on checking the brake oil situation.
