The hanging heart finally let go.

"There is something wrong with your brakes, fix it and try again!" After the second retest still failed, the tester came out of the car and said to me, and immediately walked into the testing hall.

"The testing is so strict?" I thought to myself with a thump in my heart. Normally, I don't feel any abnormality in the braking. Even during emergency braking, the ABS anti-lock brake is turned on normally. I had no choice but to leave in anger.

I went for testing on March 4 and did not get a qualified report, but I got this reminder. Is it good or bad? I have no idea. After coming back, I went to the repair shop the next day for inspection and maintenance.

"Well, I checked your car and there is no problem with the brakes, but there is something wrong with the right rear wheel shock absorber, leaking oil! You can see that the left rear wheel shock absorber is dry, and the right rear wheel is wet. Also, the water content of your brake fluid is high, it is best to replace it. Put the brake fluid test pen into the brake fluid, the green light should be on, and yours is the yellow light. However, when the left rear wheel is started, the brake is locked. It's a little tight. The right rear wheel can move normally, but the left rear wheel can't rotate. It's probably time to replace the brake cylinder. The tire tread has also exceeded the minimum limit and needs to be added. "The maintenance man checked it and told me.

"Can it be repaired?" I asked.

"This cannot be repaired, it can only be replaced." He said helplessly.

The tall maintenance man said to me while changing my oil, "You can't pass the brake test, but if we drive it, we will definitely pass it."

"Why?" I said.

"There is cooperation between our repair shop and the inspection station." He said.

It turns out that a slogan was posted on the testing line of the testing station: fair and open, transparent and just. Anyone who comes to chat with you is guaranteed to be a scalper. Scalpers still exist!

Those open scalpers do not exist, but those hidden scalpers in repair shops that cooperate with inspection stations still exist. It looks peaceful on the surface, but there is an undercurrent surging behind it.

On March 10, all the accessories to be replaced were prepared: four Magxis MA-708, a bottle of special brake fluid, a bottle of ethylene glycol antifreeze, and a rear wheel brake cylinder , a right rear wheel shock absorber, came to the repair shop.

The replacement of other parts went smoothly, except for the brake cylinder. The reason is that the threads of the new brake cylinder do not match the old screws. The threads of the new brake air pump are coarse threads, and the threads of the old brake air pump screws are fine threads. The new brake cylinder cannot be installed.

"I removed your brake air pump and checked it. It is good and there is no problem. It will definitely pass after changing the brake fluid!" the boss said to me. "Maybe!" I thought to myself, "Why don't we go test it again on Monday. If it passes, it means it's not a problem with the brake pump. If it fails again, the brake pump must be replaced." Okay, that's it. It’s decided.

March 11th? Monday? 9:00 a.m.? Testing line

I originally planned to go to the testing station in the afternoon, but then I thought about it and decided to go earlier and get this done. So that a hanging heart can be settled.

The inspection station starts working at 8:30. There are not many small cars for inspection at this time, and most of them are large trucks. Cars and trucks are two different detection lines. I was in line behind two vans.

The detection line mainly detects three major items: lights, brakes, and exhaust gas. I handed the key to the inspector and waited anxiously. I was still worried that the brakes would not pass again.

I looked at it and slowly drove into the detection line. The lighting is finished! Brake test completed! Exhaust gas detection completed!

The staff drove the car to the parking lot, parked it, and walked out. I immediately went to meet him.

"How was it?" I asked.

"Very good, no problem, passed." He said.

"Thank you! Thank you!" I said repeatedly. Finally passed!

It turns out that I went to the inspection line for inspection last Monday and found a brake problem. In fact, it was not a real brake problem. Thinking about it carefully, it should be a problem with the tires and brake fluid.

I just changed these two items and the test passed smoothly. Anyway, one thing was finally accomplished. The hanging heart was finally let go.
