Quickly put the car upside down and find a lot of tools and materials such as wrenches, vise, knives, scissors, old inner tubes, emery cloth, glue, etc.

First, loosen the valve core nut, then use a tool to gently separate the black outer tire from the bicycle rim. Then peel off the rear tire from the steel rim with your hands, and then pull out the red inner tube inside the black outer tire.

Conduct a visual inspection. Be sure to check very carefully, otherwise if the inspection is missed, you will have to do this series of "work" again.

After careful inspection, I found a small hole. I looked at other places and checked several times, but no other holes were found.

Pull the inner tube and place it on the knee of your left foot to "fix" it. Use the thumb and index finger of your left hand to make a "bow" shape to press the inner tube. Use the emery cloth to polish around the small opening with your right hand. While polishing, blow it away gently with your mouth.

The small plastic particles that have fallen should be polished away to remove the dirt and plastic on the surface. If the clean plastic inside is exposed, the polishing is almost "passed". Continue to polish evenly to create a circular area of ​​about one centimeter. Then pick up a piece before

Polish the old inner tube that has been cut off to make it look similar to the opening area of ​​the inner tube, then cut it off with scissors and smooth the edges for later use.

Take out the glue bottle. Because it is not used often, the cap and body of the bottle have been glued very tightly by the spilled glue. It cannot be opened at all by hand. You can only use a modifying knife to pry. Pry it open and then use a modified knife.

Dip the knife into an appropriate amount of glue and apply it evenly on the inner tube polishing area. Apply it well and let it dry. Then dip some glue and apply it evenly on the cut piece of spare plastic skin. Wait for the glue surface on both sides to solidify. Quickly pick up the spare plastic.

Carefully paste the leather against the inner tube and press it firmly. Wait for about half an hour for the glue to completely dry and the adhesion to be firm.

After patching the tire, I immediately found a large basin and filled half of it with water. Then I laid the car flat and inflated the inner tube. When it was inflated, I held it with both hands and pressed it into the basin to check.

Are there any bubbles there? If there are bubbles there, it means it is broken and needs to be repaired. If there are no bubbles, congratulations, there is no problem.

Observe the newly patched area first. The effect is pretty good! There is no air leakage. Then press it next to each other and press it into the water section by section to check.

Fortunately, after inspection, no air leakage was found in other places. Otherwise, this inner tube would have kept me busy most of the night.

Quickly put the bicycle upside down again. Deflate the inner tube, put the inner tube into the black outer tire, then align the valve core with the valve core hole of the steel rim and pass it out, screw on the nut to fix it. Then press and embed the other parts.

into the steel rim. Then inflate the inner tube. When inflated halfway, stop. Tap the outer tire lightly with a wrench to make the inner and outer tire stick more evenly and tightly. Then continue to inflate until it can no longer be pressed with your thumb.

The bicycle tire has been repaired. The water has been poured out. The large basin has been put away. Then check the front brake and the rear brake. There is no problem with the front brake, but the rear brake is a little loose and it will not stop the car in an emergency.

Come on, hold the brake connecting rod with a vise in your left hand, and hold the brake adjusting nut with a vise in your right hand. If you pull it in, it will be "tight", and if it is pushed out, it will be "loose".

After adjusting it, you can see that the steel rims, steel wires, and frame have all lost their luster because they have not been used for a long time. Simply, we just kept doing it and found "kerosene" to give it a clean and beautifying look.

After struggling for a long time, the whole bike finally became "radiant" again. It felt a little brand new. I pushed the bike to the wall and parked it, and couldn't help but press the bell on the faucet.

The crisp ringtone of "Dingling bell..." startled me. Afraid of waking up my brothers who were sleeping upstairs, I quickly wrapped my hands around the bell so that it could only emit the smallest, somewhat dull "Ding."

At that moment..." Sound.

Get some water and wash your hands first, squeeze some toothpaste and brush your teeth, then wash your face and feet.
Chapter completed!
