Brake disc protection plate friction abnormal sound.
The causes of abnormal ring of brake disc protection plate friction may include brake disc deformation, serious wear, foreign bodies between brake pads and brake discs, missing or damaged brake disc fixation screws, brake disc rust, new car run-in period or just changed brake pads, vehicle into water or wading, emergency brake ABS start, brake pad installation reverse or inconsistent model, the use of inferior or excellent brake pads, brake pump different Brake fluid is often deficient. The methods to solve these problems include replacing or repairing the brake disc, polishing the edge of the brake disc or replacing the brake disc, removing foreign matter, filling or replacing the brake disc fixing screw, wiping off rust for a period of safe driving, no need to deal with normal phenomenon, installing the brake pads that match the model, replacing other brands of brake pads, checking and repairing the brake pump and adding brake fluid.
In addition, between the brake disc and the brake pad may be mixed with small stone debris and other foreign objects, which will produce abnormal friction when stepping on the brake, resulting in the brake disc squeaking. The way to solve this problem is to carefully check the brake disc and remove the small sand and gravel. The running-in problem between the brake pad and the brake disc may also lead to abnormal sound, this situation occurs in the new car or just changed the new brake disc, is a normal phenomenon, as long as the normal use, waiting for the brake disc running-in is good, the abnormal sound will gradually disappear.
In solving the problem of abnormal sound of the brake disc, you should also understand some preventive measures, such as regularly checking the degree of wear of the brake system, and timely replacement of severely worn parts, is the key to maintaining the health of the brake system. In addition, the correct use of the brake system can also reduce the occurrence of abnormal sound of the brake disc, and avoid sudden braking and long-term braking.
Automobile brake disc rust treatment method:
1, this is very common and normal, because the brake disc is metal, and there is no protection, directly exposed to the air, resulting in oxidation rust;
2, if there is only slight rust on the surface, then we can use the continuous braking method to remove it, of course, this is to ensure safety and does not affect the premise of public transport, driving, gently step on the brake, so that the brake pad and brake disc friction will be the surface "polishing" can be;
3, if the rust is very serious, we had better drive the vehicle into the repair shop, remove the brake disc, polish the rust with sandpaper, check whether the brake surface is abnormal, after the installation of the road test, on the flat road at 70km/h speed, brake several times to ensure that there is no anomaly.
1, if it is to adjust the brake pedal stroke, there is a nut below the pedal can be adjusted. 2, if it is to adjust the gap, now the general car caliper can brake disc, or between the lead shoe and the brake drum, the gap is self-debugging, no manual adjustment. 3, can only adjust the hand brake, the foot brake can not be adjusted, if low can exhaust air try.
Automobile brake system is also called automobile brake system. The function of the braking system is: to force the car to slow down or even stop according to the requirements of the driver; Stationing stationary vehicles under various road conditions, including on ramps; Keep the speed of the car going downhill steady. Then the next small series will give you a detailed introduction to how to adjust the tightness of the car brake.
Ways to loosen the brakes:
Look at the thickness: the thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner with continuous friction in use. Professional technicians suggest that when the naked eye observation brake pad thickness has only left the original 1/3 thickness (about 0.5cm), the owner should increase the frequency of self-test, ready to replace. Of course, individual models due to wheel design reasons, do not have the conditions to see the naked eye, need to remove the tire to complete.
According to the road conditions and speed control direction, take off the high-speed gear, and quickly blast a foot of empty oil, the high-speed gear into the low speed gear. In this way, the engine will have a lot of traction resistance and reduce the speed quickly. In addition, while changing the low speed, the handbrake should be used in combination, but pay attention to the handbrake can not be pulled tight, nor can it be pulled too slowly. If it is pulled too tight, it is easy to "lock" the brake disc, which is likely to damage the transmission parts and lose the braking ability; If it is pulled too slowly, the brake disc will be worn and ablated and the braking function will be lost.
