The owner may not be familiar with the performance of each part of the car. For the brake failure, people may only find out when the brake abnormal sound or braking force suddenly drops. However, the problem is that if the situation is found at a high speed, the consequences are unthinkable. In fact, we can use the small "signs" in the usual use to determine the brake system problems, and these "signs" are really It may be ignored by everyone. First, tremble when braking This situation is mostly seen in the old body, because the use of wear, brake disc surface roughness has been a certain degree of misalignment. Therefore, it is advisable to choose to use the lathe CD process for grinding, or replace the brake pads (for older cars). Second, the steering wheel will always deflect to one side when the brake is stopped. This kind of situation is actually what we commonly call “skewed brakeâ€. The main cause of the fault is the uneven force caused by the brake pump's left and right sub-pumps on the brake pads. In the driving process, due to the fast rotation speed of the brake disc, the difference in the non-uniform action of the sub-pump during rapid friction is very small, and it is difficult for us to feel it. However, when the vehicle is stopped quickly, the difference is obvious. The wheel on the fast side will be given priority and the steering wheel will be deflected. This situation may need to replace the sub-pump. Third, before the drive needs hot car more than ten minutes to have braking force The brake system is provided by the engine to push the caliper to clamp the brake disc (disk brake), or to force the brake disc to friction with the brake drum (drum brake). So, like the above situation, it may be that there is a loss of pressure in the pressure-providing transmission pipeline, which makes it impossible to provide braking power in time. In this case, check the brake master cylinder's vacuum booster hose and the engine's excuses for cracking or loosening. Fourth, the brake does not return When you step on the brake pedal, the pedal does not rise and there is no resistance. This phenomenon is that the brake does not return. It is necessary to judge whether the brake fluid is missing or not; whether there is oil leakage in the brake cylinder, piping and joints, and whether the components of the main pump and the sub-pump are damaged.
large size can be filled with more powder. It also can change to any color and Surface Treatment, like rubber, UV spray, plating. the parts of plastic injection will be assembled together in our assembly workshop. Its size is 119.6*63MM, and surface treatment is electronic plating. There are some different colors for bottom and top cover. The molds are existed, so we can produced for client at anytime. And it is good for us to control the quality and timing.
