Baotou Beiben Heavy Truck Accessories shares with you the brake pipeline, including steel pipes and flexible hoses, which are connected together with connectors to transfer the brake fluid obtained from the master cylinder to each wheel brake. Pipeline leakage will cause failure of the brake system. Therefore, the brake pipeline is a very important part of the system. Pay attention to inspection and maintenance

In daily life, it is necessary to regularly check whether there is leakage to ensure that it is always in good condition,

Check the steel pipe and hose to ensure that the vehicle will not contact the wheel or body due to vibration when moving or when the steering wheel is fully turned to one side.

Check whether the brake pipeline hose is twisted, worn, cracked, bulged and aged The brake pipeline must be replaced even if it is slightly damaged. In the ordinary inspection, there should also be strict scale standards. If the pipeline is found to be bent, flattened and blocked, it must be replaced with a new one.

Power steering is a new technology to increase comfort in automobiles. It can automatically provide steering force when the driver is turning, thus reducing the steering labor intensity of the driver. Power steering oil is a medium oil filled in the power steering system, which plays the role of transmitting steering force and buffering. At ordinary times, check the power steering oil pipe joint every day for oil leakage, fracture, wear, distortion, etc., and check the height of the power steering oil level

A inspection method for oil level inspection height:

Place the vehicle on a flat ground; Start the engine and turn the steering wheel several times in neutral to raise the steering oil temperature to 50 ~ 60 degrees; Turn the steering wheel to the left and right limit positions for several times at idle speed; Check the difference between the oil level in the oil storage tank after the engine is started and stopped. If the difference is more than 5mm, exhaust the oil; If the liquid level rises quickly after flameout, it indicates that the abandonment is incomplete; If there is air in the system, the booster pump and control valve will make noise, which will reduce the performance of the oil pump.

B Method of changing power steering oil:

Lift the front wheel with a jack, the anti support stool under the vehicle or the vehicle with a lift; Remove the oil return pipe from the oil storage tank and block the oil storage tank with a plug; Insert the oil return pipe into a suitable container; Disconnect the high-voltage line of the engine, and turn the steering wheel repeatedly to the limit position while starting the engine; After the steering oil is drained, connect the oil return pipe, fix it firmly with clips, and add the specified type of power steering oil into the oil tank; Bleed the steering system

C Other bleeding methods for power steering:

Disconnect the high-voltage line of the engine and start the engine several times. At the same time, turn the steering wheel to the limit position for 5-6 times. At this time, observe the oil level in the oil tank shared with you by Baotou beiben heavy duty truck accessories. If it cannot fall to the lower end of the filter in the oil tank, add steering oil at any time. If the air is bled at idle speed, the air may be absorbed by the oil, so the air shall be bled at startup. Plug in the high-voltage line and start the engine. Turn the steering wheel left and right until there is no bubble in the oil storage tank and the steering wheel is at the limit position for no more than 10 seconds; Determine whether the steering oil is mixed and whether the oil level is higher than the specified value; When turning the steering wheel from left to right, check whether the oil level changes, and bleed again if there is any change. When the engine is stopped, the oil level rises suddenly and there is air in the surface system,; If there is air in the system, the booster pump and control valve will make noise.

The tightness of the power steering system shall be checked when the vehicle is hot. Perform the following steps:

Quickly move the steering wheel to the limit position on both sides of the left and right, and keep it still. At this time, the pressure in the system can reach the maximum value of Z;

Visually inspect the steering control valve rack seal power steering pump;

Check whether there is oil leakage at the oil pipe joint. If there is leakage, replace the seal;

Check whether the oil tank of Baotou Beiben Heavy Truck accessories is lack of power steering oil, and if so, check whether the sealing of the steering system is intact;

If the gear strip seal in the power steering gear housing is not sealed, the power steering oil may flow into the bellows sleeve. At this time, the steering mechanism should be disassembled and the sealing ring replaced.
