Riding a Kawasaki H2 to chase the high-speed rail, the school beauty was moved to tears

Why does the little guy use so much rear brake?

Without the lap speed data of this track, Xu Hong didn't know whether Qin Chuan's lap speed was fast or slow. He only knew that Qin Chuan used the rear brake many times during this lap, which was very unreasonable.

Niu Fei, who came with him, also noticed this. Qin Chuan actually used so much of the rear brake, almost in every corner. What was going on?

Even if it’s an error correction, it doesn’t need to be done so much.

Looking straight ahead, it was only when Qin Chuan came into contact with the rear brake that he realized how difficult this thing was.

The control of timing, including the precise control of the rear brake lever, is not something he can adapt to in a short time.

No wonder no one in China knows how to do this.

The rear brake is on the right foot, and the accuracy of the foot is far less sensitive than the hand.

He could squeeze the front brake as much as he wanted, but the rear brake was difficult and took time to get used to, not to mention his leg was injured.

After trying it, Qin Chuan also discovered the duality of the rear brake.

Rear brakes don’t only have advantages, they also have disadvantages.

Success comes from the back brake, failure comes from the back brake. If you control the timing well, it can make you faster. If you don't control it well, the risk of crashing will be great and the error tolerance rate will be extremely low.

It's easy to crash if you control one front brake, not to mention the need to control one more rear brake this time.

In the past, he could guarantee that he would not make a mistake, but with the addition of the rear brake, Qin Chuan himself was not sure whether he would make a mistake in today's race.

The track in front of me is a small track composed of old tires, with few straight lines and many curves.

Turning back and forth, Qin Chuan maintained a good rhythm. This track was very suitable for him to practice rear braking.

Before entering the next corner, Qin Chuan held the brake with his right hand, downshifted with his left foot, and then rear brake. When approaching the apex of the corner, Qin Chuan stepped on the brake lever with his right foot and slowly pressed down, using the rear brake to slow down, front and back. Applying the brakes and turning into the corner, it can be seen with the naked eye that Qin Chuan's car is shaking violently and its center of gravity is unstable.

"It was still too hard and the timing was wrong."

After turning on the gas and exiting the corner, Qin Chuan made some movements with his upper body. After turning over, Qin Chuan prepared to brake before the next corner. This time, he planned to apply the rear brake lightly.

This thing is too difficult to control.

Racing cars mainly use front brakes. The reason for using front brakes is because when the car decelerates, the center of gravity will be forward, and the downforce of the front wheels will be greater than that of the rear wheels, so the front brakes perform better.

The center of gravity is the key to the use of the rear brake. When to use the rear brake is closely related to the location of the center of gravity of the body, which is also one of the difficulties of rear braking.

Although he followed the book, Qin Chuan never managed the timing well.

According to the master's operation in that book, the rear brake is mainly used in three periods of time.

The first one is when collecting oil.

Before the bend, the car accelerates in a straight line. The driver puts his right hand on the right handlebar and twists the accelerator downward. This is the action of opening the accelerator. After reaching the braking point, the right hand quickly returns the accelerator upward, and then squeezes the brake lever. The action of returning to position is called oil recovery.

At the moment when the oil is reduced, apply the rear brake. This is the first point of use of the rear brake.

In fact, the engine brake has already intervened to reduce the oil, but the center of gravity of the car body has not yet completely moved forward. This rear brake is very helpful in reducing the vehicle speed.

After applying the rear brake, quickly downshift with your left foot.

The function of this step is to ensure that after you confirm the braking point, the rear wheels will always decelerate, brake first, and then downshift.

The rear brake fills the gap between the front and rear wheels before downshifting and at the end of the throttle.

Qin Chuan can't do this step yet. This step of back braking may seem simple, but you must know that when doing this action, both the left and right feet and hands are moving, which requires extremely high coordination of the body.

Moreover, although the braking speed dropped quickly after this kick, the car body was very unstable. With his current car control skills, it was easy to make mistakes, and the gain outweighed the loss.

After the front brake intervenes, the front shock absorber is pressed down and the rear wheel is almost suspended. The rear brake is useless at this moment.

The next rear brake application point is in the second half of tracking braking, that is, when entering the corner with braking and approaching the center of the bend. When the body tilt approaches the maximum angle and approaches the center of the bend, it is the second rear brake application point.

When the car enters a bend, due to tracking braking, the front brake is slowly released after approaching the apex of the bend. At this moment, the center of gravity of the body begins to slowly move from front to back, and the front shock absorbers gradually open.

At this time, there is slight downforce on the rear wheel, and using the rear brake can help decelerate. At this time, the rear brake does not have much effect in decelerating, but if you do this in every corner, the lap speed advantage it brings is terrifying.

Compared with before, the rear brake here is much simpler, because the downshift action has been completed at this moment, Qin Chuan only needs to control the strength of the front brake and the rear brake, and will not be as busy as before.

Gradually release the front brake and apply the rear brake gradually.

As for this last point, it is when exiting the corner. When exiting the corner, turn on the gas. If the front wheel is off the ground at this moment, to prevent the ECU from intervening and cutting off the power, you can lightly apply the rear brake.

Qin Chuan has only mastered the basics of the latter two points so far. It will take some time to adapt to whether he can use them in the main game.

Qin Chuan only came off the track at [-]:[-] in the morning. After a whole morning of training, he finally found the critical point where the rear brake would not cause the car to shake. Qin Chuan was absolutely sure of this race.

The car drove slowly to Longwan Circuit, and Qin Chuan sat in his seat to take a quick rest.

Seeing Qin Chuan's appearance, Jiang Yue next to her felt heartbroken, but she couldn't speak.

......

Longwan Circuit, [-]:[-] in the morning.

Qin Chuan hurried to the p room and started to warm up and change into leather clothes. There were still twenty minutes before going on stage, but fortunately there was still time.

"Brothers, good afternoon, everyone, I am your anchor Ling'er."

Today's main event attracted more than [-] spectators, making it the largest event in Xiangjiang City this year.

In the corner of the front row of the auditorium, a lady wearing a black stocking uniform was holding a cloud platform and pointing it at the track for a live broadcast. She had a sweet and soft face.

"Water friends, is it hot there? The weather here in Xiangjiang River is so cool."

The sweet lolita sound came into the live broadcast room from the microphone on Liu Luoling's collar.

In just five minutes after the broadcast started, more than [-] people flooded into Liu Luoling's live broadcast room. He is considered a mid-level anchor with considerable traffic on the Douhu platform.

Liu Luoling frowned secretly at this, and thought to herself, as expected, the popularity of csbk is still not as popular as some big competitions, because there are so few people.

Unfortunately, she is a bit pressed for time and has no time to go abroad this week.

"The Xiangjiang River is so cool? Believe it or not! We are almost turning into dogs from the heat."

"It's upstairs, and so is our place. It's extremely hot without the air conditioner."

"Air conditioning, do you need air conditioning? I'm just lying naked on the bed."

"Good guy, you are still ruthless."

The barrage responded quickly. Liu Luoling had long been accustomed to seeing these inappropriate remarks. She ignored the barrage and focused on the track.

"Hey kids, the race starts in five minutes. Let's see who are the drivers today."

Although she is a female anchor, Liu Luoling's knowledge of racing is not bad at all. She is not inferior to some professional commentators at all. It can be said that she has good looks and strength.

"It's great. There is another game to watch. The main thing is to watch Ling'er. Who doesn't love Sister Loli Yinyu?"

"What's so interesting about csbk? Ling'er, why don't you broadcast international events?"

"Shit, domestic ones are the best. Who wants to watch those foreign racing cars?"

"But there are few overtaking scenes in China and they are not exciting."

The lsp on the barrage filled the screen like crazy. After Liu Luoling briefly answered a few barrage questions, he focused on the game.

"I heard that csbk has a new driver today, and he is a handsome young man. When he comes out later, I will give you a close-up view."

Before Liu Luoling could finish his words, a large number of riders poured out of the P room and the tire warm-up lap began.
