@ Fu Niu-Share the story of her car-Do it yourself to change brake fluid in detail
JenniferLucas 
9 I have been driving 40000 kilometers for more than 3 years, commuting to and from home. I still feel good. I usually maintain and maintain myself, and I firmly do not ask for help. It is also very powerful. I have never lost my temper with me. The car is in good condition and the fuel consumption is economical. Let’s say this. I have to talk about how to change the brake oil myself.
Every car has a braking system, which plays a vital role in the car, and it is also the cornerstone of a car safety.
Braking system function: when the car is driving, it slows down or stops according to the driver’s request, or decelerates or temporarily stops in time when going downhill and in various road conditions, as well as parking.
Types of brakes:
Automobile braking system is generally divided into two types: 1, air brake (air pump driven by engine, compressed air stored in a gas storage tank, when the driver presses the brake pedal, so that the gas executes to each brake sub-pump, to achieve the purpose of deceleration or parking) is generally used for large and medium-sized trucks, passenger cars, and so on.
2, oil brake (this is easy to understand, that is, the use of brake oil, also known as brake fluid, when the driver presses the brake pedal, brake fluid produces pressure, so that each brake sub-pump work, to achieve the purpose of deceleration or parking) is mostly used in agricultural vehicles, mini-transport vehicles, cars and so on.
Braking mode: there are drum brakes and disc brakes, also known as disc brakes. This is easy to understand, so let’s not say any more. Today, we mainly talk about the oil brake system and how to change the brake oil by ourselves.
Tools for preparing materials: two bottles of original DOT4 brake oil, (single bottle 500ml) pump (if there is no pressure for shampoo bottles), 2 mineral water bottles, one 6 “hose, one M10 opening wrench (small movable wrench is also available) (also need an assistant to help you step on the brake pedal, that is to say, it takes 2 people to change the brake oil)
Specific steps: 1 to remove the original brake oil, 2 to add new brake oil, 3 to discharge each sub-pump old brake oil. 4 discharge the old brake oil of the clutch pump, 5 test run.
Oil discharge sequence:
The order of discharging the old brake oil should be far and then near, one after another, and then the front wheel. Because most brake lines are “X” type, in order to prevent the mixing of new and old oil, the oil change should start from the left or right rear, such as 1 left rear wheel, 2 right front wheel, 3 right rear wheel, 4 left front wheel. (but this is not absolute, because different models are for reference only)
Start the operation
Open the cover and find the brake oil kettle (in front of the vehicle battery). Unscrew the lid and take out the filter.
No more than three years at the latest, because the brake oil has strong water absorption, and the moisture increases over a long time, which will lead to the rust of the brake sub-pump, the non-return wheel increases the resistance, the fuel consumption will rise, and the moisture will produce air resistance due to frequent braking for a long time. The braking effect decreases, and the braking distance can not be ignored.
Let’s start with the right rear wheel.
At this point, open the oil screw counterclockwise with an M10 wrench, and the old brake oil will flow into the bottle. Tighten the screw immediately after waiting for the brake oil to stop flowing, and tell the car assistant to loosen the pedal. Then step on it a few more times (every wheel does it this way)
At this time, let the assistant observe in time to add brake oil to the oil kettle, the liquid level is not too low to avoid entering the air.
Then continue in order, left rear wheel, right front wheel. Add brake oil to the kettle in time at the end of each wheel. Prevent the line from entering the air.
(I drilled the bottom of the car to put oil, and I didn’t take pictures at the back and the front of the right, hoping to understand)
In fact, there is no change in the clutch brake oil, most family cars are brake clutches share an oil pot, Ruihu 3 is no exception. In other words, the clutch also uses brake oil, so the clutch also releases the old brake oil.
If you go to the repair shop to change brake fluid, the repairman generally will not take the initiative to change the clutch fluid for you. 1 It is too troublesome or increases the working hours. 2 The repairman ignores it, or simply does not think that the clutch needs to be replaced as well. 3 The unscrupulous technician would not tell him at all. Who is so easy to tell you like me? Hahaha.
Final test: The clutch is obviously much lighter than before. The test brake and clutch are normal.
I am purely a personal hobby. I usually like to check and maintain my car by myself. I am happy to share, use, maintain, repair, maintain, decorate, etc.(does not represent professionalism, but is for reference only). I hope to help my car friends. Thank you for your support.
