How Often Will The Brake Be Replaced?
To determine how often to replace the brake, in addition to often run long-distance comparison of the provincial brake, the most important thing is the driving method is appropriate, Brake Pad such as driving the amount of advance, if you can find a good grasp, often do not have to brakes.
In general, a pair of brake pads with 100,000 km no problem, with good, or even up to 150,000 km. But for each driver to brake the frequency is not the same, it is difficult to define how long the car brake pads need to be replaced once.
The only way is, in the routine inspection, look at the degree of wear of the brake pads, Brake Pad if the critical point, you have to immediately replace.
Here are some special cases to note:
1, novice brakes generally step on the more consumption will be larger.
2, automatic transmission than the manual file fee brake pads, because the automatic shift is to rely on the accelerator pedal and brake pedal.
3, often open the city's car, brake pads will be faster than the highway traffic quickly open. Because often open the city car, often to stop and go, with the brakes will be more. Brake Pad Take the road may take tens of kilometers to slow down or stop, with the opportunity to brake is relatively small.
4, load a large car, brake pads loss. The same speed of the case of slow down the brake, the weight of the car inertia, the need for friction on the brake pads on the large, so wear large.
How to check whether the brake pads change?
1, see the thickness: a new total thickness of the brake pad is generally about 1.5cm, when the brakes to reach 0.3mm brake time (not including the thickness of the iron Oh), Brake Pad it must be replaced. With the use of continuous friction will gradually thinning the thickness.
When the thickness of the brake pad has been visually observed only about 2/3 of the original thickness (about 1cm). 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, Brake Pad it is possible that the basic brake pads have lost friction.
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, Brake Pad it is recommended to 4S shop or regular repair shop to check to determine whether the need to replace The
4, see the warning light: the brakes on the brakes whether the 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.
Replacement of brake pads:
1, disc brake brake plate replacement is relatively simple. Remove the tires, loosen the brakes of the screws, you can win the brakes, and then put on a new, the whole process up to 5 minutes, and does not require any adjustment.
2, drum brake replacement is slightly more difficult to remove the wheel, and then remove the brake drum, and then to replace the brake pads, pay attention to the new brake pads and brake drum between the coincidence of the situation, coincide bad, and sometimes Need to be polished; when assembling, adjust the gap between the brake pads and the brake drum.
