(Summary description)Inspection method of brake pads: Measure with a brake pad measuring ruler. The thickness of the new brake pad is generally 1cm. If the brake pad is less than 3mm, it should be replaced. Usually you can see the general situation of the brake pads through the gap of the wheel hub with a flashlight. If the thickness of the outer brake pads of the caliper is less than 5mm, you need to remove the tires to check the brake pads on the inner side of the cylinder. Precautions when selecting brake pads and replacing brake pads: When choosing brake pads, you must look at the friction coefficient of the brake pads. The friction coefficient represents the performance index in the constant speed friction test. The friction coefficient of the brake pads of ordinary household cars is between 0.35-0.55. The larger the coefficient, the better the braking effect. The coefficient of friction is marked on the brake pad packaging. Attention should be paid when replacing: 1. The depth of the friction groove on the edge of the brake disc. If the depth is large, the brake pads need to be polished and the chamfer is polished to prevent abnormal noise. 2. When the brake pad is installed, the friction material should be in contact with the brake disc. If it is installed backwards, the back plate will contact the brake disc. There will be no brake or abnormal brake noise when installed. 3. The new brake pads with screws and accessories must be replaced with new ones, because there is thread glue on the new screws to prevent the screws from loosening. 4. After the brake pads are replaced, you should step on the brakes several times. After stepping on hard, check the brake oil level. Only when the oil level is normal can you start driving. And when driving, you must step on a few more brakes, so that the brake pads and brake discs are fully run-in, and the braking effect is the best. The hazards of the brake pads not being replaced in time: 1. Abnormal sound of the brakes, there is a low and loud rubbing sound when you step on the brakes, which is very harsh. This is the friction between the brake disc and the back plate, causing damage to the brake disc. 2. This is very serious, the brakes fail, and there is a dangerous situation without brakes.
