How brakes work
If something is said well, you must know why it is true. However, many drivers do not know the braking principle of large trucks.
It’s not that trucks still use drum brakes. In fact, no matter what method is used, the principle is the same, that is, when the brake pedal is stepped on, the lever will be activated, and the lever will push the brake pump, and the brake disc and brake pads will brake through friction. Generate a braking force to prevent the large truck from moving forward.
1.Apply the brakes intermittently
As all truck friends above already know, most trucks still use drum brakes. The cost of drum brakes is low, but one of the biggest shortcomings is poor heat dissipation. If this type of drum brake is used on a car, the difference will not be noticeable.
However, the problem of poor heat dissipation can be clearly seen in large trucks, because the body of large trucks requires longer braking distance and stronger braking force. Therefore, frequent braking will cause poor heat dissipation of the brake pads. Failure, this is also a common problem in brake failure.
2.Trucks are speeding and overweight
If the brake pads suddenly fail, there may be some uncontrollable reasons, but brake failure caused by overloading and speeding of trucks is 100% a man-made accident. This is why it is emphasized that truck drivers must not speed or overload. Excessive consumption of the life of the vehicle, resulting in aging and damage to parts, will naturally increase the risk of problems.
3.Insufficient maintenance on a daily basis
Very few truck drivers check their brakes carefully before setting off. Regular maintenance is not possible, not to mention, daily inspections feel very cumbersome. Little do you know that it is such a carelessness that makes you lose control of the vehicle at critical moments and lead to serious consequences.
If you want to do your job well, you must first sharpen your tools. I believe all truck drivers understand this. Brakes and seat belts can really save lives at critical moments. Spending a few minutes checking them and practicing regular maintenance can save you a lot of trouble.
4.Bad driving habits
Many truck drivers believe that they can do the above three things, not overloading or speeding, driving strictly in accordance with traffic regulations and not flashing frequently. He said that he also pays attention to daily maintenance.
But the last thing is bad driving habits. The difference between an experienced driver and a novice driver. Many people will come up with a bunch of reasons. In fact, one of the simplest ways is to be cautious and veteran drivers have one foot on the road. Will not lift off the brake pedal.
Always maintaining control of the vehicle is a better driving habit for experienced drivers, but young drivers or drivers with less experience always have the energy of a newborn calf who is not afraid of tigers and can run to 100 miles, and will never run to 100 miles. 99 miles.
As soon as you hit the road, you forget all about keeping a safe distance and start letting yourself go. In an emergency, you step on the accelerator and the brake pads suddenly fail, and the consequences are unimaginable. Good driving habits are the basis for ensuring driving safety.
