Can the brake pads of large trucks be used after they smoke downhill and pour cooling water?

You can continue to use it.

Large trucks are large in size, and the driver's vision is blind.

There are many inner wheel differences formed when turning is the fatal triangle area of large trucks, so that pedestrians and non-motorized vehicles cannot be observed in the process of turning and changing lanes.

Causing traffic accidents. The police said that pedestrians and non-motorized vehicles should keep a distance of more than 3 meters from large trucks during driving.

The bad driving habits of many truck drivers lead to repeated traffic accidents, large trucks running red lights are very common, mostly due to the fast speed and hurry, often too late to brake, coupled with the long-term dust of the vehicle, the license plate is defaced, but also makes some drivers have a fluke psychology for traffic violations.

In addition, most trucks are overloaded, the overall weight is too large, and it is particularly fuel-intensive to step on the brakes and then start, so many drivers run red lights in order to save fuel consumption.

According to industry insiders, if large trucks strictly abide by traffic rules, there is no profit margin at all, and in the long run, it will cause losses, and even exceed the economic losses caused by accidents.

The brake pads of the large truck smoke downhill and put the cooling water on it, and it can not be used in the future, because it is too dangerous, and the time of the brake of the large truck has a buffer, and he smokes when he brakes immediately, indicating that it is already very worn, so it will be very dangerous to continue to use, so it will be very dangerous to replace it quickly, replace it with a new brake pad, for your own safety and the safety of others, and quickly change the brake pads.

It's already smoking, and you can't play much role in drenching water, you can use it, but the brake system doesn't cool down so quickly The braking effect is definitely not as good as normal temperature, and it is common sense to see the downhill boiling water. Don't wait for overheating.

The brake pads are smoking, which means that the slope you go down is too long, and it is okay to cool it with water, but often like this, the effect of the brakes is not very good, especially when the car is heavy, and the car cannot be braked. These are for your reference only.

As far as I know, because of the large load capacity, the large truck must be poured and cooled from the auxiliary water tank when going down the long slope, otherwise the brake drum will produce high temperature and high heat due to long-term high-speed friction, causing brake failure, and more serious will cause the wheel ** to cause fire and cause a major accident of car destruction and death. Spray-cooled brake drums generally do not pour brake pads unless they are cracked.

When a large truck goes down a long slope, it should first turn on the cooling water to flush the brake pads to prevent the brake pads from overheating and causing brake failure. Brake pads that have been washed with cooling water can continue to be used without damage.

Check the braking effect as soon as possible, and if the difference is not significant, you can continue to use it. It is recommended that you disassemble and inspect as soon as possible.

Brake pads should not be watered if they are smoking. Metal brake discs are cast, cast iron is very wear-resistant, and the cost is lower, but cast iron is very brittle, and it is easy to crack when cold in a high temperature state. What's more serious is that the high temperature and water may quench the surface of the brake disc, resulting in an increase in the hardness of the surface layer and affecting the friction coefficient, which directly leads to the brake is not as strong as before.

In hot weather, people are easy to "catch fire", and vehicles are also easy to "catch fire". Recently, I have read some news reports about the spontaneous combustion of cars. What causes spontaneous combustion of automobiles? What should I do if the brake pads smoke in hot weather?

There are many reasons why brake pads smoke, and you can only deal with the specific reasons by finding out the specific ones:

1. If the temperature of the brake pad is too high and the smoke is caused by frequent braking, do not brake frequently for a long time.

2. If the organic content in the brake pad formula is unqualified or the manufacturing process is unstable, it will also smoke, and the solution is to replace the brake pad.

3. The brake pads are not installed in place, resulting in friction and smoke from the brake pads, and the brake pads need to be reinstalled.

When the brake pads smoke, it is recommended to park the car on a flat bottom without slope, let go of the handbrake, hang neutral gear, and then push the cart yourself. If not, it is another possibility, that is, there is a leak of the rear brake fluid dripping on the brake disc, and the high temperature generated during braking causes evaporation and even combustion smoke. No matter which of the above reasons or any other problem, it is recommended that riders go to the repair shop for an inspection, after all, safety comes first.

Automobile brake pads are consumables and must be replaced when the brake pads are worn to the warning line. Let's talk about what to pay attention to when replacing brake pads.

1. When replacing, the brake pads provided by the original spare parts should be replaced, only in this way can the braking effect between the brake pads and the brake disc be good and the wear and tear should be small.

2. When replacing the brake pads, you must use special tools to push the brake cylinder back. It cannot be pressed back with other crowbars, which can easily cause the brake caliper guide screw to bend and make the brake pads limb stuck.

3. After replacing the brake pads, be sure to step on the brakes a few times to eliminate the gap between the shoe pads and the brake disc.

<> "The owner has just changed the brake pads, but found that after stepping on the brakes, there is a phenomenon of smoke. So can you water brake pads when they smoke?

When the brake pads are smoking, you can't water them by hand, which is not good for the brake pads and brake discs.

Because the brake disc is generally cast, the wear resistance is very high, but it is easy to crack when cold under high temperature conditions; Moreover, in the case of high temperature, water may cause the surface of the brake disc to be quenched, so that the hardness of the surface of the brake lead sheet increases and the friction coefficient is affected, and finally leads to the situation that the brake is weak, and this operation method is not advisable.

When the brake pads appear to smoke, as the owner, you need to stop the car as soon as possible, and you need to go to a professional maintenance shop to conduct a comprehensive inspection of the vehicle to ensure the safety of the owner in the process of driving; In order to prolong the service life of the brake pads, the owner should try to avoid frequent braking.

The main purpose is to prevent the failure of the brake pads, the truck goes down a long slope, and the brake will cause the brake hub temperature to be too high for a long time, and then the brake will fail or even **, so most of them are equipped with drip brakes (air brakes can be installed), the purpose of which is to avoid the high temperature of the brake hub so as to maintain the braking effect.

Generally, the water is discharged before going down the long slope, and the temperature of the brake hub can reach more than 150 degrees when braking, and the boiling point of the water is only 100 degrees, so there will be smoke in the hub when braking.

Frequent braking when fully loaded leads to adhesion or thermal decay, which affects the braking effect and is prone to accidents. Installing a water tank on the top of the cockpit, leading drip irrigation to the brake drum position in each wheel, and constantly dripping water to cool down the brakes can alleviate the above situation. Hope it helps!
