Why do the two front brake pads of Chery A516 keep rubbing the brake discs?

It may be due to the fact that the brake disc is relatively thin, which causes uneven heating when braking, so pay attention to it, change the brake disc, and try.

You can touch whether the brake pads are flat, after driving 2 to 30,000 kilometers, you can replace the brake pads, and the new ceramic brake pads will not cause uneven wear of the brake pads and produce brake noise.

You check whether the brake disc and brake pads are thin, if it is a brake thing will not only sound when starting the car, the brake is also alarmed, grinding to a certain extent, the alarm steel plate on the brake will grind the brake disc, there is a very starry sound, mixed with small stones or something will also sound, the brake disc brake pad grinding to the place with impurities will also sound, the car is jacked up with a jack, rotated to judge, or remove the tire and rotate to judge. If you don't have tools, you should go straight to the repair shop and let them professionally check it.

Hello, according to the situation, it is recommended to replace the brake pads in time. Brake pads that are too thin or too hard with burrs can cause friction against the brake disc.

I'm glad to have your question, I hope to help you hand Chery A516 two Qianlong sand ten pieces, has been a frosted disc ornament Why first check it, our brake explosion is there? Do not return to the pattern and other phenomena, and then check it, our brake pads are recommended to go to a professional laboratory for inspection.

The new brake pads were installed without sanding the edges around the **.

The main thing to see is that the thickness of the brake pads is less than 50-20mm, so you need to replace it immediately. The thickness is shown in the figure

You can use a flashlight to stick in with a ruler and look sideways.

1. Analysis of possible causes.

1. It is the lack of necessary maintenance of the brake system, there are too many impurities in the brake master cylinder, the sealing is not tight, the vacuum booster pump fails, the brake oil is too dirty or the air resistance occurs after the mixing of several brake oils after heating, the brake master cylinder or sub-cylinder leaks, and the air leakage of the gas tank or pipeline interface;

2. It is due to improper operation that causes the failure of the parts;

3. Due to serious overload, under the action of gravitational acceleration, the inertia of vehicle movement is increased, which directly leads to brake failure.

Second, the treatment method.

1. Control the direction according to the road conditions and speed, disengage the high-speed gear, and at the same time quickly blast the empty fuel and shift the high-speed gear into the low-speed gear. In this way, the engine will have a lot of traction resistance and the speed of the vehicle will be reduced rapidly. In addition, the handbrake should be used in conjunction with the low-speed gear shift, but it should be noted that the handbrake should not be tightened or pulled too slowly.

If it is pulled too tightly, it is easy to make the brake disc "lock", and it is likely to damage the transmission parts and lose the braking ability; If it is pulled too slowly, the brake disc will wear and ablate and lose its braking effect.

2. Use the bumper, carriage and other rigid parts of the car to rub and collide with natural obstacles (rocks, trees or soil slopes) on the side of the road to achieve the purpose of forcibly stopping and getting out of danger, and reduce the accident loss as much as possible.

3. If the brake fails when going uphill, it should be reduced to medium and low gear in time to maintain sufficient power to drive uphill to the top of the slope and stop. If you need to park on a half-slope, you should keep the forward low gear, tighten the hand brake, and the personnel with the vehicle should use stones, skids and other objects to jam the wheels in time. If there is a backward slippage, the rear of the car should face the hillside or the safety side, and the headlights and emergency lights should be turned on to attract the attention of the vehicles in front and behind.

4. When the downhill brake fails and the speed of the vehicle cannot be controlled by the mechanism of the vehicle itself, the driver should decisively use natural obstacles, such as rocks and trees on the side of the road, to cause resistance to the car. If you can't find a suitable terrain or object to use for a while, in an emergency, you can move one side of the car closer to the side of the mountain, and gradually reduce the speed of the vehicle by rubbing to increase the resistance.

5. The vehicle should step on the brakes when going down a long slope or a steep slope, regardless of whether there is a situation or not. It can not only test the performance of the brakes, but also buy time to control the speed of the vehicle when the brakes are found to be out of order, also known as predictive braking.

3. Preventive measures.

Do not ignore the daily maintenance of the brake system, in order to prevent the occurrence of brake failure, please maintain the brake system in time, regular maintenance and overhaul is essential, for the safety of life, you must not ignore the regular maintenance.

Note: Check whether the brake shoes are in good condition, and do not overuse the brakes, hang the low gear when going downhill, use the brake of the engine to let the car drive, supplemented by the foot brake; Avoid severe overloading to prevent brake failure.
