Tips: How to Change and replace Brake fluid
Preparations for replacing brake fluid
1. It is best to operate by three people: one is responsible for draining the oil, one is responsible for stepping on the brake pedal, and the other is responsible for adding new oil. There can also be two people: one is responsible for draining the oil, and the other is responsible for applying the brakes and refueling.
2. Before changing the oil, you can unplug the brake lamp on the fuse holder, so that the brake tail lamp does not light up when you step on the brake pedal, which can prolong the life of the bulb. After the change, I want to go back.
3. A more formal method is to prepare a transparent soft plastic tube with a length of 50 cm and an inner diameter of about 6 mm and a transparent plastic bottle with a capacity mark. When replacing the brake fluid, insert one end of the hose into the oil discharge port of the sub-cylinder and the other end into the plastic bottle to avoid splashing and observe the replacement amount.
4. Prepare 1-2 bottles of new brake fluid, usually one bottle is enough. In order to clean it more cleanly, two bottles are also fine. You can reserve them for later replenishment, but it is better not to use the old oil when you replace the brake fluid next time. The normal brake system will not leak brake fluid, and the fluid level of brake fluid will only drop as the brake pads gradually become thinner.

Operation:
1. Put the vehicle on the trench or lift it with a lift.
2. One person under the car, remove the rubber dust cap on the oil drain port, install the two ends of the prepared transparent hose into the oil drain port and waste oil collection bottle respectively, and then use a wrench to loosen the oil port screw in a counterclockwise direction , And the person in the car repeatedly stepped on the brake pedal. At this time, the brake fluid will be sprayed from the drain port. To determine the fluid level in the brake fluid reservoir, add new brake fluid as the fluid level drops. Tighten the oil drain screw after the oil is clear.
3. The person in the car repeatedly stepped on the brake pedal to the highest point and stepped on the brake pedal to not loosen the foot. The person in the car loosened the oil port screw, tightened after the brake fluid was sprayed, and notified the person in the car to loosen it. Repeat the above operation several times until there are no air bubbles in the brake fluid discharged. Consider adding new brake fluid to the fluid level in the brake fluid reservoir as the fluid level drops.
4. Go to another round and repeat the steps 1 to 3 above.
5. The order of replacing the brake fluid should be farther and nearer, that is, start from the far end of the brake pipeline first, then the first wheel, then the front wheel. If you are particularly concerned, because the brake pipeline has an "X" layout, in order to avoid mixing of new and old oil, the oil change and bleed can start from the left rear or the right rear. For example, the first one puts the left rear wheel and the next one puts the right front Wheel, then the right rear wheel, and finally the left front wheel.
6. After the four wheels have been replaced, the road test is completed. If the brakes are found to be soft and not sensitive, please repeat step 3 to deflate, and follow step 5 in order. Consider adding new brake fluid to the fluid level in the brake fluid reservoir as the fluid level drops.
