It is said that there are many kinds of oil in the car, but their main role is nothing more than the effect of lubricating and maintaining related parts, thus playing a good role in protecting the normal work of related parts. the brake fluid we are talking about today (commonly known as brake oil) is a vital liquid for our vehicle brakes.
In fact, before the brake oil, I also checked the relevant information on the Internet, and many motorists mistakenly thought that the brake oil needed to be changed only when it was dark. This is a big misunderstanding. As for why I do not copy and paste it here, please check it on the Internet by yourself.
Below, I would like to share with you the whole process of changing the brake fluid and related precautions.
We have been black for three years, and we should have changed it a long time ago according to the standards of the maintenance manual (I only noticed it after reading the maintenance manual recently. )
The steering wheels of cars in our country are all left-rudder cars, which means that the cockpit is located on the left side of the car, and the corresponding throttle brake clutch pedals are also located on the left side, so the connected parts of the pedals are also located in the engine cabin in front of the cab. As can be seen in the picture above, the brake oil kettle and the ABS are located directly in front of the cab.
The white one above shows the brake oil kettle, the bottom of the oil kettle is the brake master pump, the black brake vacuum pump behind, and the ABS pump on the right, these are the components of the main brake body in the cabin.
In fact, before I went to the store to change the brake oil, I opened it myself to see the quality of the brake oil. It was all right from the outside, but this is the wrong way to identify the effect of the brake oil. The most accurate method still needs to be tested by relevant equipment to know its actual effect. (it is not recommended that you open the brake oil lid at will. If you have to open it, please clean up the sundries and dust of the kettle first to avoid falling into the brake oil.)
The volume of the brake oil will change with the temperature, and the kettle body has a vent, which will absorb some moisture and impurities over time, which will affect the original effect of the brake oil for a long time. The best way is to change the brake oil regularly. (safety components should not be careless)
Our character belongs to want to do it for a moment do not want to wait, in advance with the store to make an appointment to change the brake fluid.
Change the brake fluid machine this time. (brake fluid charging and releasing machine)
The tool No. 11 opening wrench needed to replace the brake fluid this time.
Material brake fluid 1L grade DOT4 (be sure to change the brake fluid for the vehicle according to the manufacturer’s oil standard)
The materials and tools are ready, and the master has set to work.
First, remove the oil kettle cover, and then connect the interface of the brake engine to the kettle lid.
After the brake engine is connected to the lid of the kettle, add the new brake oil to the machine.
Do not lift the vehicle until the preparatory work is ready.
The car has risen.
After the vehicle was fully lifted, the master placed garbage bins under all four tires to facilitate the flow of discarded brake oil into the bins.
The position of the brake oil outlet of the front and rear wheels can be seen by the mark above.
The 1 marked in the above picture is the oil outlet dustproof cap and 2 is the oil outlet.
The above picture shows the dustproof cap of the oil outlet on the brake caliper.
After turning on the machine, the master can loosen the oil drain with wrench 11 and the brake oil of the original car can be discharged through the extrusion of the machine.
You can clearly see that the brake oil of the original car is draining out of the oil outlet.
The master is judging the result of oil discharge according to the brake oil consumption in the brake engine.
I am not idle, holding a disposable cup in the position of the oil outlet to pick up some discharged brake oil, smelling nothing and looking clean and bright, but do not be misled by its color, brake oil is difficult to turn black, unless your road conditions are particularly poor (the main working environment of brake oil is circulating in the pipeline, which is different from the working environment of engine oil, so the color of brake oil is generally clean)
The whole process of oil drainage lasted about five minutes.
After checking that the oil discharge is normal, begin to tighten the oil outlet.
Don’t forget to tighten the back cap at the oil drain.
The master is using a sponge to clean the place where the brake oil has been drenched.
Wipe the sponge clean, then clean and blow dry with high pressure QIANG
After finishing the above work, the vehicle landed.
After the vehicle lands, remove the brake oil machine interface.
The color of the brake oil just changed is much brighter than that of the original car.
There is a picture as proof, the comparison picture before and after the brake oil is changed.
After the master covered the oil kettle, the whole process of changing oil was over.
For a vehicle that has just changed the brake oil, remember to hit the brake several times before starting. Because the work of the brake vacuum pump stops in the process of vehicle replacement, it is necessary to step on a few brakes in order to brake normally.
After stepping on a few brakes, the whole process of changing brake oil is over.
With regard to the cost of replacing brake oil, the man-hour cost is 84 yuan, and the material cost is 76 yuan, totaling 160 yuan.
There are many pictures above, whether to finish or talk about the details of the process of changing brake oil and related matters needing attention.
Brake oil machine oil change effect is similar to our medical syringe effect, the machine in the operation of the original brake oil through extrusion, but in the process of oil discharge, there will be more or less residual brake oil, if you want to drain the original car oil, you need to use a few more bottles of brake oil.
Just after changing the brake oil in the first few days, do not step on the brake violently, the newly changed brake oil may have air in the domestic demand for several days of running-in squeeze to make the oil in the pipeline smooth. (there is usually no big problem with changing oil in the machine, but we still have to pay attention to it.)
According to the professional standard after changing the brake oil, the maintenance manufacturer who changes the brake oil for us can deliver it to us only after the test run of our vehicle. (this time the store also changed the brake oil for Heilang before handing over the car to me. During the test run, I only talked and forgot to take photos.) for the sake of our driving safety, this link is essential. If some riders meet the shop owner and forget to test the car, be sure to remind the shop owner to test the car.
Brake oil is a vital liquid on the car body. It is recommended to change the brake oil every 2 years or 50000km, or the saying that the safety parts should not be careless, and the cost is not very high, it is much cheaper than we change the oil.
Today, the whole process of changing brake fluid is over, and I hope the riders will give me some advice.
