Vehicles in the process of driving, ceramic brakes are constantly in the wear and tear, for this time to do a good job maintenance inspection work, once the ceramic brake frame is a serious calculation, should immediately replace the new brake pads. So what is the wear and tear? Wear to what extent need to be replaced?
1, see the thickness: a new brake pad thickness is generally around 1.5cm, with the use of continuous friction will gradually thinning the thickness. When the thickness of the brake pad has been observed by the naked eye, the original thickness of about 1/3 (about 0.5 cm) is left. The owner will increase the frequency of self-test, ready to replace the. There are 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.
2, the feeling of intensity: driving on the road when the brakes, if it is very difficult, there is always a soft feeling, often need to step on the brakes deeper to achieve the previous braking effect, when the emergency brake will obviously feel the pedal position Low, it is possible that the basic friction has been lost friction, and this time must be replaced, otherwise it will lead to serious accidents. 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.
3, listen to the sound: If the light brake at the same time with the "iron rub iron," the slightest sound or clamor sound (there may be brake pads in the beginning of the installation of the role of running), this time the brake pads must be immediately replace. Because the brakes on both sides of the limit logo has been directly friction brake discs, that brake pads have exceeded the limit. 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, it is recommended to 4S shop or regular repair shop to check to determine whether the need to replace The
4, the brake warning light: the instrument panel on the brake warning light is lit as the brake should not be based on the judge. Some high-end cars will have a brake warning light and in general the brake alarm line only before the brake pads have. When the warning light is on, if it is changed at this time, it is already quite dangerous. Because this warning system is a direct sense of the thickness of the brake pads, and some are in the brake pads have been completely finished, the brake oil so extreme decline, will make the warning light. If it is the latter, wait until the warning light is on, the brake pad metal base and the brake disc are already in the iron mill state, this time, in the tire near the edge of the rim to see the bright iron. Therefore, we recommend that the brake pads be checked regularly.
