Electrical connector

Car in addition to a very small number of important electrical connectors using gold contacts, the rest of the majority of joints are used copper – zinc alloy, under normal circumstances, its reliability is guaranteed, but if the car long-term high temperature, high humidity , Bumpy environment to run, these joints may have loose, rust, bad contact and other failures, and some strange electrical problems are mostly produced. Therefore, in routine maintenance, should focus on checking the car on the computer, sensors, fuel injectors and other components of the joints.

Chassis parts

From the point of view of use, the chassis components are actually more prone to problems than the engine, but in routine maintenance, many people often overlook the inspection of the chassis components. Chassis prone to failure of the site mainly concentrated in:

1, Baotou North Mercedes-Benz accessories shock absorber: oil spill is a precursor to damage to the shock absorber, in addition, on the bad road driving bumps significantly increased or braking distance is also a sign of damage to the shock absorber.

2, the suspension control arm sleeve: after the damage of the plastic sleeve will be a deviation, pendulum and a series of failures, even if the four-wheel positioning also to no avail. If you carefully check the chassis, coat damage is easy to find.

3, Baotou North Mercedes-Benz accessories steering rod: steering rod slack is a serious security risk, therefore, in the routine maintenance, we must carefully check this site. Practice is simple: hold the lever, forced shaking, if not shaking, it shows that everything is normal, otherwise, it should replace the ball or rod assembly.

4, exhaust pipe: exhaust pipe is the most vulnerable parts of the car one, do not forget to look at the maintenance. Especially with three-way catalytic converter exhaust pipe, should be carefully checked.

5, Baotou North Mercedes-Benz accessories universal joint dust cover: Do not underestimate the universal dust cover outside, it is not only dust effect, but also to prevent the loss of grease around the universal joints, dust cover once damaged, Grease will soon be lost, due to dry grinding, universal joints are easy to damage.

Tires

Should pay attention to the regular replacement of tires, a group of tires and then durable, can not use a lifetime, some people work easily, the use of low frequency car, a group of tires after a few years, the tread surface is intact, but in fact The performance of the tire will increase with the aging and slowly aging, the quality gradually reduced, if you do not know this, since that “the surface looks good” that the tire is no problem that is the wrong view.

When cleaning tires, first remove the tires in the stone and other inclusions, check the tire with or without bubbling, delamination, laceration, change, aging and other failures; followed by the removal of tires, the rim for rust, check the tube and Lining with or without damage or wrinkle phenomenon, according to the provisions of air pressure, tire tipping or transposition. In addition, check the tire and the wing, the car floor, leaf spring, fender and so on whether the phenomenon of friction.

Battery

Batteries are the key to the electrical system. In modern cars, a large number of electrical devices are used, and the battery is not working properly and will affect the performance of many devices. For example, in the automatic transmission of the car, if the battery is not normal, will make this car can not start. Therefore, it is necessary to always obtain a stable power supply.

Check the battery level, if the liquid level is located in the upper and lower two between the line is considered appropriate. At the same time should also check the tank surface difference. If the liquid level is insufficient, you can unscrew the battery cover, pour the distilled water to make up the liquid level.

Check the battery terminals and use the iron brush to remove the dirt from the terminals. If the wiring clamp is seriously defaced, you can use sandpaper to wipe the wall along the wall, grinding dirt.

Brake pads

Usually we will be on the dashboard brake warning light is lit as the brake shoe to judge the basis, but this is the last bottom line, if at this time for, has been quite dangerous.

To remind you that although all vehicles have this warning system, but some are directly sensitive to the thickness of the brake shoe, while the brake shoe is completely finished grinding, the brake fluid so extreme decline, will make the warning light From. 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, in each time into the factory maintenance should check whether the brake pads can be used, and early replacement of life near the bottom of the brake pads, and not only believe that the warning light.
