As automobile one of the most important parts of the braking system, is directly related to the safety of the vehicle, while the self-test of the brake pads is particularly important. Cruze owners released microblogging, an auto repair experience how to check the thickness of the brake pads and replacement posts, and a lot of other owners favorable.
Method 1: Look thickness
A new brake pad thickness of about 1.5cm thickness With the use of continuous friction will gradually thinning. Naked eye observation of the thickness of the brake pads have been remaining 1/3 of the thickness of the original (about 0.5cm) around, the owner is necessary to increase the self-test frequency, and ready to replace. Of course, individual models wheel design reasons, do not have the view of the conditions to the naked eye, the tires need to be removed to complete.
Both sides of each brake pad has a raised flag, this flag is the thickness of the two or three millimeters, which is brakes thinnest replacement limit, must be replaced if the thickness of the brake pads have been parallel with this flag. Therefore, when the thickness of the brake pads close to this mark, the owner is necessary to be observed at any time to prepare, but not tire removal by the naked eye is difficult to accurately observe many models in the brake pads are too thin instrument handbrake lamp position prompt will be relatively self-test on convenient.
Brake pads is not strictly according to the car environment and driving habits change intervals, generally about sixty thousand kilometers traveled should consider replacing. Naked eye observation that thin brake pads should ask the technician in the maintenance checks, because the naked eye would have been error, professional repair station by caliper tighter than the naked eye.
Method 2: listening to the sound
If tapping on the brakes while accompanied by iron rub iron "hiss, the brake pads must be replaced immediately. Because of the limits of identity on both sides of the brake pads have direct friction brakes, prove that the brake pads have been over the limit. Often when this happens, replace the brake pads at the same time to meet the inspection of brakes, the sound appears brakes have been damaged, even at this time to replace the brake pads still can not eliminate sound serious when you need to replace the brakes .
In addition, some of the poor quality of the brake film hard spot, it will also produce abnormal sound generally abnormal sound so will wear off after a period of time disappear.
Often already too late when the voice heard brakes, the brakes more or less will be damaged. Compared to the price of brake discs brake pads to be much higher, and therefore suggest that you wash check the brake pads to avoid damage brake discs things appear.
Method 3: feeling the intensity
Brake was very difficult, it is a basic loss friction brake pads, this time must be replaced, otherwise it will lead to a serious accident. This method is relatively abstract, seat of your pants may be some bad grasp therefore very important to develop a good self-test habits. Another braking effect to reduce brake oil consumption increases, replace the brake pads at the same time to focus on the situation to check the brake fluid.
Many of my friends in the de Paul habits of their own purchase and maintenance materials to some repair shop maintenance is recommended to purchase brake pads to the 4S shop or a regular service shop for the purchase and replacement, because the current market, especially the brake pads of auto parts city product categories variety, true and false is indeed difficult to distinguish, and the price is very different, and some thirty or forty dollars simply unqualified, and therefore recommend friends not freeloaders not distinguish the authenticity of the ability to buy substandard products endanger traffic safety.
