Listen to experts

"Master, is this?" Shen Zhengjun looked puzzled when he saw the master take out something thirty centimeters long from his bag, which was much thinner than a flashlight.

"Click!" Li Wenkai pressed the switch and swung hard. It turned out that the thing that was thirty centimeters long instantly turned nearly one meter, and there was a cross-shaped handguard block.

This is three-section stick-swinging. Later, when Li Wenkai thought about it, he bought two more.

The total length is 95 cm, and there is a conical tip at the end of the handguard. If you encounter something that is despair, just hit the head - ko!

"You can hold this for self-defense. When you encounter something that is not eye-catching, you can beat it to death as long as it doesn't take any life. Don't get hurt like your junior brother." Li Wenkai pressed the switch, pushed it hard to the ground, and flipped the stick back.

This was the first time Shen Zhengjun saw such a handy self-defense thing, and he loved it very much. He soon became familiar with it. Li Wenkai helped his apprentice carry it on his belt.

"Master, do I look like a hero now?" Shen Zhengjun deliberately exposed his coat outside and exposed the stick inserted in the black leather hood at his waist and said to Li Wenkai.

"Like, like a rag-collection hero." Li Wenkai looked at his apprentice with a smug face, "Let's go quickly and see if he can get a job today." It has been open for a few days, and there is no business order.

"Master, don't worry, you will definitely find a job today." Shen Zhengjun left happily.

While riding a bicycle, he touched the stick around his waist from time to time. In Li Wenkai's opinion, he wanted someone to fight with him at this time.

At noon, a car drove to the repair shop at the unit's transportation office.

"Master Li, please help me see. The brakes of this car are not very good. This time I go far, please help me see the brakes." The driver Peng Hongwei came out of the car and saw Li Wenkai and said. After that, he took out a pack of Warrior cigarettes from his pocket and handed them to Li Wenkai.

Peng Hongwei and Li Wenkai also knew each other. When they went outside to disassemble the accident car, they were driving the car that Peng Hongwei drove, and they were also intimate with Li Wenkai's father.

"Thank you, Uncle Peng." Li Wenkai said to him after seeing him taking the initiative to light a cigarette for him.

"Xiao Li, I'm going to go out for a long door this time. The brakes of this car are not very effective. Please help uncle completely solve it so that I won't drive it unsteadily." Peng Hongwei said.

"Uncle Peng, don't worry, I'll help you with it in a good way, and check the engine again." Li Wenkai said.

This is related to human life. As a regular undergraduate auto repair graduate, Li Wenkai has his own professional ethics and knows how to do it.

"Hehe, this really corresponds to the old saying, there are people in the court who are easy to do, and we are now arrogant." Peng Hongwei was also happy to hear Li Wenkai's promise.

If my unit didn’t have this ability before, it would be different. Now that I have my own repair shop, it would be more delicate.

Everyone knows that Li Wenkai's skills can be fixed by a scrapped car that goes into a ditch. Braking is not a matter of moving your fingers, and the engine is even more of a problem. He watched Li Wenkai assemble the parts of an engine.

Li Wenkai drove the car outside for a while, returned to the factory, and told Li Guangyuan and the others to say, "Lose down the wheel screws on both sides of the back, then use a jack to lift it up, and put on wood..." Li Wenkai began to guide everyone.

Li Guangyuan and the others have been idle for a few days, and they have all their strength. Of course, they do this. Li Wenkai only stands on the side to guide them.

This is exactly what the other four wanted.

Soon, the tire on the left behind was removed, then the wheel hub was removed, and the brake pads inside were opened.

"Look, the brake pad has been worn seriously. Look at the nails that have been exposed. Look at the inside of the wheel hub. These wear is worn by a metal nail. The wear marks are caused by this nail, so the brake effect is naturally poor." Li Wenkai pointed to the wheel hub and said to the brake pad.

Yuejin brand nj130 brake uses drum brakes, and the two semicircular arc brake pads are opened with a pneumatic brake pump. The brake pads rub against the inner side of the wheel hub to finally form a braking effect.

Now that the effective part of the brake pad has been worn out, the brake effect is naturally not good.

"You have removed the other few, and I'll check the brake lines again." After Li Wenkai said that, he drilled under the gutter and asked the driver to go to the cab to step on the brakes.

When I saw that there were also pipe joints from the air tank to the pneumatic sub-pump that also leaked.

At this time, the nj130 brake is an air brake. The two huge pneumatic sub-pumps drive the lever to drive the brake pads and the wheel hub to start braking.

There are two pipes that leak. This one needs to be replaced, but it cannot be repaired. Braking is related to personal safety. As a regular car repairer, Li Wenkai has his own measurement standards. What can be repaired and what must be replaced have his own measurement standards, not to mention that this time it is still running a long distance.

Li Wenkai took two tubes and handed them to the driver Peng Hongwei, and asked him to go to the unit's logistics office to see if there was any, and then buy whatever was not available.

The remaining joints have leaking air, cut an inner tube and polish it when used as the sealing ring.

The inner side of the wheel hub is pulled to the factory for the turning workers to process it. These are trivial things for the old lathe masters.

After checking the brake pads, Li Wenkai replaced them if they should be replaced, and put them back if they should not be replaced.

Fortunately, there were four middle-aged veterans helping, and Li Wenkai only directed everyone to work throughout the process.

"Thank you all for a while. I'll tell you the theoretical knowledge of this brake system." Li Wenkai said to everyone as he was busy and very serious.

Li Wenkai also thinks that some of the techniques that are not core are taught by everyone. After they understand these ordinary techniques, they will be more relaxed.

"Thank you, Brigade Commander!" Li Guangyuan shouted excitedly when he heard that the brigade commander wanted to teach him real skills.

Everyone also cheered. When they heard that the leader was going to talk about the brake system, they became more busy.

Logistics Department of Hongxing Machinery Factory.

"Why did I change 4 brake pads at once?" Liu Yuanzheng, the head of the logistics department, felt bleeding when he saw Peng Hongwei getting 4 new brake pads.

"Look at this old one, can this be used? The nail is exposed. Master Li from the repair shop said that he must change the new one before he can get out of the car, otherwise he will not be allowed to get out of the car. You can do it yourself." Peng Hongwei said, pointing to the four old brake pads that were replaced.

"This..., I want to ask the factory manager." This brake pad is not easy to get. Now I use 4 at once, so there are only 2 in the warehouse. I need to ask the factory manager for this.

"Please give me a try!" Peng Hongwei said.

This is not what I said, it is what the expert Master Li said.

"Director Liu, how about it?" Peng Hongwei asked when he saw the other party coming back dejectedly.

Liu Yuanzheng sighed and said, "The factory manager said he wanted to listen to experts. Master Li said he would change it if he said he would change it, otherwise no one would take responsibility if there was an accident." After Liu Yuanzheng said that, he asked his subordinates to issue an order, and then Peng Hongwei signed it.

"Take it away." Liu Yuanzheng said heartbrokenly as if he was marrying his daughter.

"Thank you, Chief Liu, haha." Peng Hongwei moved out with 4 brake pads.

The other wheel hubs were also quickly processed and placed behind a Yuejin license plate outside and asked colleagues to pull them back to the repair shop.

Li Wenkai asked Li Guangyuan and the others to prepare, and as soon as the things came back, they put them back.

With Li Wenkai's explanation before, everyone has a rough understanding of the entire brake system, and it will be much faster to install it back this time.

Four strong men, in groups of two, Li Wenkai checked and quickly installed them.

"Uncle Peng, try again. I just re-checked and repaired the engine. This time, there should be no problem running a long distance." Li Wenkai said.

"Haha, I've never been so arrogant, thank you." Peng Hongwei felt much more at ease when he heard that Li Wenkai had helped him repair the engine.

Where did this be treated like this before?
