Today we are starting from the data,
Let’s take a look at the brakes should pay attention to those problems!
Different braking distances at different speeds
Measured brake distance
40km/h is the speed limit standard for no central line roads in some cities.
Braking distance is 6.9 meters
The speed limit of some urban main roads is 60km/h.
Braking distance is 14.22 meters
80km/h is the speed limit standard for some urban expressways.
Braking distance is 25.24 meters
100km/h is the speed commonly used in domestic high-speed,
Braking distance is 39.12 meters
Different braking effects on different road surfaces
The ground temperature is different for different braking effects.
Dry ground friction is the biggest,
The brake effect is very good.
But as the ground temperature changes,
There will also be some fluctuations in the braking effect.
For example, in the summer, the ground is heated by the sun.
The friction coefficient between the tire and the ground becomes smaller.
The braking distance will also be slightly longer than usual.
Of course, people who don’t drive can also know that
Humidity has a greater impact on the braking effect.
Do you want to drive in the rain and snow weather more carefully than usual!
a slippery road under rain and snow,
Will increase the braking distance,
Especially during the fast driving of the car,
The tires are less in contact with the ground,
Therefore, in the rain and snow weather, slow down and pay attention to safety!
Pre-judgment in advance warning
Brake light of the front car
During normal driving,
By observing the brake lights of the front car,
To judge the timing of the brakes.
But if you encounter a car emergency braking distance is not enough,
You can also avoid collisions by changing lanes.
Don’t grab these signs,
Be prepared to slow down or brake at any time.
Special case special treatment
When the downhill needs to slow down,
Don’t brake on for a long time,
After pressing the brake pedal,
Quickly lower the gear and drive at low speed.
Take a long step on the brakes,
Will cause the brake pads to heat up,
Thereby the braking force is reduced,
Serious damage to the brakes,
So by changing the gear,
Control the power output to reduce the speed.
Step on the brakes after the wading section
The vehicle drove out of the wading section,
There is moisture left between the brake pads and the brake disc.
At this time, without affecting the normal passage of the car,
The brake system can be dried by intermittent braking.
Do not slam on the brakes when the tire is broken.
Never slam on the brakes when you have a flat tire.
Slamming the brakes may cause the car to slip or roll over.
Be sure to hold the steering wheel with both hands.
Do not hit the steering wheel.
The body will float or roll over in the direction of the punch.
After the puncture, you must first stabilize the body and keep straight.
Slowly slow down the speed,
Stop by the side and wait for the rescue.
“Brakes can be said to be very important when driving.
For the brakes,
Also need a lot of actual combat and practice! ”
