Brake pads do not need to be in accordance with the number of miles to change, a few simple ways can see the wear.
Friends who love cars may have a clear concept that the car itself is consumable, and the parts of which will be replaced in time with the increasing service life of the vehicle. But many people do not know when to change the brake pad, some people say that you can according to the maintenance manual said every 30,000 kilometers replacement, but because everyone's driving is not the same, road conditions are not the same, so the brake pad wear situation are not the same.
1、Look at the shape -- look at the thickness
The new thickness is generally about 1.5cm, and will gradually become thinner with constant friction during use. When it is observed that the thickness of the brake pads is only about one-third of the original thickness (about 0.5cm), the owner needs to increase the frequency of self inspection and be ready to replace them at any time. If some car models do not have the conditions for visual inspection due to wheel hub design, they need to remove the tires to complete.
Each brake pad has a raised mark on both sides, the thickness of this mark is about two or three millimeters, which is also the thinnest replacement limit of the brake disc, if the thickness of the brake pad has been parallel to this mark, it must be replaced. Therefore, when the thickness of the brake pad is close to this sign, the owner should be ready to observe at any time. However, it is difficult to accurately observe with the naked eye without disassembling the tires. Currently, many car models may indicate the position of the instrument handbrake light when the brake pads are too thin, which is relatively more convenient for self inspection.
2、Hear the sound --Listen to sound
Except for the run-in phase of the new brake pads, if there is a sizzle of "iron against iron" when the brake is tapped, the brake pads must be replaced immediately. Because the limit marks on both sides of the brake pad have directly rubbed the brake disc, proving that the brake pad has exceeded the limit. When this happens, the brake pad should be replaced at the same time with the brake disc inspection, this sound often occurs when the brake disc has been damaged, even if the replacement of a new brake pad still can not eliminate the sound, serious need to replace the brake disc.
In addition, just replaced the bad quality of the brake pad has a hard point, this will also produce abnormal sound, in general, this abnormal sound will be worn off after a period of time.
3、Check the force -- feel the force
According to the normal driving habits, if the brake feels very difficult, it is possible that the brake pad has basically lost friction, at this time must be replaced, otherwise it will cause a serious accident.
This method is relatively abstract and can only be mastered by experienced drivers. It may be difficult to grasp it based on feelings, so it is important to develop a good habit of self inspection. In addition, the reduced braking effect will lead to an increase in brake oil consumption, so when replacing the brake pads, it is important to focus on checking the condition of the brake oil
No matter what kind of method is used for self-inspection, it is necessary to conduct more professional and careful inspections when reaching the standard line of 30000 kilometers. Relevant items can also be inspected during normal maintenance and upkeep. Braking is the most important means of ensuring the safety of personnel inside the vehicle, and should not be careless
