How to change car brake fluid and how to change car brake fluid?

The method of replacing the brake fluid is: 1. Turn off the vehicle, open the engine compartment cover, use a syringe to pump out the oil in the oil storage tank, and pump it to the bottom of the tank; 2. Fill the oil pot with new brake fluid; 3. Use a jack to jack up the vehicle, starting from the rear wheel, and remove the tire; 4. Find the oil drain screw of the brake cylinder and remove the rubber dust cap on it; 5. Use a wrench to loosen the oil drain screw, put the rubber tube on it, and connect the other end to the oil drain bottle; 6. Go to the car and start to step on the brakes, if you find that the rubber pipe is discharged from the shallow new oil, the oil change of this wheel has been completed, stop stepping on the brakes, install the tires, and repeat the operation for the next three tires; 7. After all four wheels are discharged, observe whether the oil volume of the oil storage tank in the engine compartment has reached the lower limit, and if it reaches the end, new brake oil can be added appropriately.

1. Place the vehicle on the trench or lift it with a lift. 2. One person is under the car, take off the rubber dust cap on the oil drain, install the two ends of the prepared transparent hose in the oil drain port and waste oil collection bottle, and then use a wrench to loosen the oil port screw in the counterclockwise direction, and at the same time the person in the car repeatedly presses the brake pedal. At this time, the brake fluid will be sprayed out of the oil drain, and the liquid level in the brake fluid reservoir should be added as the fluid level drops.

Tighten the oil drain screw after the oil is clear. 3. The person in the car repeatedly steps on the brake pedal to the highest point and steps on the brake pedal do not let go, the person under the car loosens the oil port screw, and tightens it after the brake oil is sprayed clean and notifies the person on the car to release. Repeat this several times until there are no bubbles in the released brake fluid.

The idea is that the liquid level in the brake fluid reservoir should be added as the fluid level drops. 4、.Repeat steps 1 3 above to another round.

1. First of all, put the vehicle in a state of ignition, and open the lid of the brake fluid, and use a syringe to pull out all the brake fluid in it until it reaches the bottom of the tank.

2. Then you can pour new brake fluid into the fuel tank (1-2L), as for how many liters to fill, it depends on the capacity of the fuel tank.

3. Use a lift to lift the bottom of the car, of course, you can also use a jack, but it is not so convenient to operate.

4. Then find the oil drain screw of the brake cylinder and remove the dust cap on the oil drain buckle.

5. Use a wrench to loosen the oil drain screws and put the rubber tube in it. Above, the other end is connected to the oil drain bottle.

6. At this time, you can start to step on the brakes, you need to pay attention to the color of the brake fluid in the rubber tube, if the color is still relatively dark, it proves that the old brake fluid has not been drained. If the color is lighter, it means that the tire has completed the oil change, stop pressing the brakes and install the screws and dust cap back (the other three tires do the same).

7.Finally, it is necessary to observe the position of the brake fluid, and if it reaches the lowest scale, it is necessary to replenish the brake fluid.

Connect the transfer brake oil pump machine to the oil filler of the brake master cylinder, open the exhaust nozzle of the four-wheel sub-cylinder one by one, and push out the old oil while injecting the new oil, and then close and tighten the exhaust nozzle. If the brakes are weak, the air in the oil pipe needs to be drained again.

Hello! The brake oil filler port seems to be on the inside of the wheel hub, and ordinary users are not recommended to replace it by themselves, or find an auto repair shop or 4S shop to replace it.

This requires professional personnel, professional equipment, and more professional technology to replace. You need a certain method to drain oil, refuel, deflate and other processes, which is related to driving safety and your own life, so it's best not to try it.

1.The oil change process is cumbersome, but it needs to be done:

2.First, lay the car flat on the ground, turn off the engine, and pull down the handbrake. Empty the tank of brake fluid, add new one, press the brake pedal and release, then open the exhaust screw of the brake cylinder and the oil will flow out.

When the pedal reaches the bottom, turn off the spiral air. If the new oil comes out a few times, you need to refuel the oil pot in time and the air will enter. After repeating this, fill the brake fluid reservoir with new brake fluid.

Return to the driver's position and continue the previous operation until the discharged waste oil becomes clear, proving that new oil has been sprayed. In addition, the brake fluid is corrosive, so pay attention to safety when operating.

3.The first time the brake fluid was changed was because the brake cylinder of the customer's car was broken and the brake cylinder was replaced.

4.It is recommended to go to a repair shop or shop for a replacement.

How much does it cost to change the brake fluid depends on where you come to replace it. If it is a car 4S shop to replace the brake oil, of course, it is more expensive, because its own labor costs are already quite high, and the total cost is about 150 to 40 yuan (different car charging standards are different). If you go to an auto repair shop to dismantle and replace, it is relatively cost-effective, and it is very likely that you can get it for a hundred yuan.

Naturally, the most cost-effective thing must be to disassemble and replace it yourself, just the cost of buying brake fluid. Naturally, there are some friends who don't know how to change the brake fluid of the vehicle.

Brake fluid replacement process:

1.First, use an injection needle to remove all the old brake fluid in the car's fuel tank until there is hydraulic fluid in the bottom tank. With it you can immediately pour in new brake fluid.

2.Then use a hydraulic jack to hail the bottom of the vehicle, look for the oil drain screw of the brake pump, and remove the anti-fouling cap that is buckled up by the oil drain.

3.Use a wrench to loosen the oil drain screws, and use a rubber hose to connect the oil drain port and the oil drain bottle to each other.

4.At this point, you can gradually apply the brakes, not so much at the same time as observing the color of the brake fluid in the rubber hose (preferably by another person), if you find that the color is lighter, you can stop applying the brakes, because by this time all the old car oil has already been drained. (In addition, the three tires are also actually operated like this).

5.Naturally, you will eventually have to check the level gauge on the top of the car's fuel tank, and if it is lower than the minimum ruler line, you must fill the brake fluid (sitting between min and max).

Millions of car purchase subsidies.

First, the simple method requires two operations, and the time span is large.

Open the car cover, find the brake oil can, open the oil can, you can see the quality of the brake oil.

Use a needle tube to suck out all the brake oil in the oil can, and then add new brake oil, and don't let the oil splash on yourself in the process of oil absorption, so as to avoid corrosion of brake oil.

This method is simple and can be operated by non-professionals, but the oil in the brake hose cannot be completely replaced, and the brake oil in the oil pot can be sucked off again after a week and refilled with new oil. In this way, the change is more thorough.

Second, there is a more professional method, you can change the oil at one time.

Find the two oil pipes on the brake master cylinder in the engine compartment, loosen the two oil pipes with an oil pipe wrench until there is brake fluid flowing out, and when there is no brake fluid in the brake oil can, you can tighten the two oil pipes.

Fill up the brake oil, lift the car, one person sits in the car and steps on the brake pedal several times in a row, and then steps on the brake pedal without moving, and the other person uses a wrench to loosen the oil drain screw of the brake cylinder under the car, you can see that there is brake oil leakage, according to the principle of far and near, drain the oil in the left rear, right rear, right front and left front brake pump in turn.

Put down the car, fill up the oil pot, lift the vehicle, drain the oil from the four brake cylinders again according to the method from far and near, tighten the oil drain screws after completion, check that there is no oil leakage, and completely replace the brake fluid.

As our usual means of transportation, the car plays a very important role in life, so do you know how to change the brake fluid of the car? Here's the answer.

01 Changing the brake fluid can ensure the braking performance of the car, and can also play a role in maintaining the vehicle, so friends who have a car must change the brake fluid regularly and regularly.

02 Turn off the engine of the car, then open the cover of the car, find the brake oil can, and open the lid, pay attention to the brake fluid is corrosive, so do not touch the belt pei**.

03 We first need to use an oil suction device to wash out the deteriorated brake oil, which is generally more difficult to suck clean, mainly to roughly suck out the deteriorated brake oil.

04 Then carefully pour the new brake fluid into the brake oil can, to pour it full to ensure the braking performance of the car, and then close the lid of the brake oil can.

The method of changing the brake fluid of the car is: 1. Open the big cover of the car and find the brake oil can; 2. Open the lid of the oil pot and suck out all the brake oil in the oil pot with a needle; 3. Add new brake fluid.

The functions of brake fluid are: 1. The freezing point of brake oil is very low, and it has good fluidity at low temperature; 2. The boiling point of brake oil is extremely high, and there will be no gas resistance at high temperature; 3. It will not cause the erosion of metal and rubber.

The symptoms of brake fluid change are: 1. The brake indicator light alarms and flashes during emergency braking or continuous braking; 2. Take emergency braking, and the braking distance is significantly longer than before; 3. The brake pedal feels soft and weak; 4. When braking, the braking strength feels light and heavy.
