The brake disc and brake cylinder are all replaced, what is the problem with the wheel hub or hot ha

When the vehicle is moving, the brake disc is in constant motion, and when we brake slightly or semi-brake, a lot of heat will be generated due to the friction between the brake lining and the brake disc, and the maximum temperature of the brake disc can reach 800 degrees Celsius.

left and right, you can see the harshness of its working environment. Therefore, ventilated brake discs are now basically used for mid-range models, which can reduce the temperature by about 20 and up to 30. Even though the temperature can be lowered a lot, there is still a large amount of heat transferred to the hub (in simple terms, they are held together).

Also conducting heat to the hub are the tires of our vehicles, which are the only parts of the car that come into contact with the ground. The inflatable temperature in the tires can reach close to 70 degrees Celsius in summer, and even if the temperature is close to 50 percent in summer for a long time in winter, it will be almost 40 degrees Celsius. The hub heats up after driving.

Even hot is normal, unless it is a very short distance, but if you consider that the brake separation is not good, then it will obviously feel difficult to accelerate and the brake pads will wear abnormally during driving.

When the wheel of our car is abnormally hot, then we have a very simple way to judge is to touch the wheel of the four tires separately and check whether the temperature of the four tires is the same? If it is the same, then there is no doubt that our braking system is normal, if there is a hub with a particularly high temperature, and the other wheels are the same, then the wheel hub is definitely problematic through this method, it can be judged very simply and directly, whether the heating of our car wheel hub is a normal phenomenon; Abnormal causes: tire bearing damage, brake cylinder stuck, brake pads.

There is a problem. <>

It is normal for the brake pedal to be hot, if the road surface is smooth in the driving basically without the brake pedal, and the final parking is also to slide to a relatively slow before the brake stops, and the rim is hot or hot that is the gap is too small, causing the gap to be too small There are many factors, or hand it over to the manufacturer of your replacement parts for inspection, if that kind of problem can not be dealt with by this factory, do not go to this factory to overhaul or maintain.

I think this is a normal situation, because even if the brake disc and brake cylinder are replaced with new ones during driving, it will still have a serious impact on the wheel hub, causing friction and causing heating.

It may be because of the lack of oil in the bearing, if the temperature is too high, the grease in the bearing will melt and flow out, or it may be because the brake pads are locked due to the abnormal return of the brake cylinder, so it has been in a state of friction.

The bearing of the wheel hub is very badly worn, and the bearing is short of oil, so you have to check the bearing.

I'll come to you to solve this problem of envy and balance for you.

First of all, the brake pump and brake disc were replaced.

Or fever. Then I think there is a problem with the installation of the car. If the brake disc is not in place, it will also cause serious friction and heat up when braking.

This problem arose, and we reinstalled the brake disc to make it in the right position.

If the brakes are used frequently, for example, on congested roads in urban areas, this is normal. After all, brake pads.

Moderate friction brake discs. If it is hot, and stupid and the brakes blow up or can't brake.

Then prove that there is a problem with the parts made by the vehicle installation brother.

Based on the above, I think it is normal, and the new one needs to be run in after all.

Replaced the brake cylinder and soft source pipe, the brake section crack only the disc is still hot, first of all, we must understand that the wheel grip brake is to increase the friction to brake, there is friction will be heated, if you do not step on the brake heating is very serious, the brake disc has been deformed.

Brake discs. Fever. is normal.

Pin Changyou is like Xunfanguo brake disc is too hot. It's just not normal. Preferably.

Check it when you have a fever. The following tires. Is it locked?

Does the braking system work? If the brake system is lost, the system does not work. It can be driven normally.

If it is not replaced, the heat dissipation effect of the brake disc will deteriorate (the heat capacity will be reduced), which will cause the brake to be soft and the braking force will decrease, which means that it takes 40 meters to stop and now needs 50 meters to stop. If you run down a long slope in a mountainous area, it may cause the temperature of the brake disc to be too high and burn out the brake cylinder.

If the brake disc is still hot after changing the brake cylinder, it may be that the brake master cylinder is not well returned or has not exhausted the gas.

Check the brake pedal return spring and pedal free travel.

It's normal for the hub to heat up after a long period of exercise! But if it's hot after exercising, it's not normal!

If the brake pads are not thick, then it is caused by the non-return of the sub-cylinder. If the normal car is driven for a long time, it will be a little hotter, due to the heat transfer generated by the high speed of the bearing, if it does not keep stepping on the brakes and overheating, then it is the brake system with the wheel! Check it out!

Chances are, the brake pads are too tight.

If this is possible, you should check the brake system carefully.

The reasons may be: there is air in the pipeline, free travel of the pedal or the brake clearance is too large, if the brake is soft, it is recommended to go to the 4S shop to check the specific reason, the brake exhaust air, the best shot is to use the computer detector to discharge the brake air.

The brake master cylinder is also known as the brake master oil (gas), and its main role is to push the brake fluid.

or gas) to push the pistons into the individual brake cylinders.

The brake master cylinder is a one-way acting piston hydraulic cylinder.

Its function is to transfer the pedal mechanism into the mechanical energy of the staring tree.

Converted into hydraulic energy. There are two types of brake master cylinders, single chamber and double chamber, which are used for single circuit and double circuit hydraulic braking systems respectively.

In order to improve the safety of car driving, according to traffic regulations.

Now the service braking system of the car adopts a dual-circuit braking system, that is, a dual-circuit hydraulic braking system composed of a series double-chamber master cylinder (single-chamber brake master cylinder has been eliminated).

At present, almost all of the dual-circuit hydraulic braking systems are servo braking systems or power braking systems. However, on some mini or light cars, in order to make the structure simple, the brake pedal.

Under the condition that the force does not exceed the driver's physical strength, there are also some models that use a series of double-chamber brake master cylinders to form a dual-circuit manpower hydraulic braking system.

If the car orange brake cylinder is broken, the brakes will be bad, or the tires will be "locked". resulting in brake discs.

Fever. Serious ones will lead to tires and unsafe driving.

The sub-cylinder was damaged and the brake disc brake pads were not replaced in time.

It is also related to a certain extent, when the brake disc and brake pads are worn to the limit, if they continue to be used, they may cause damage to the sub-cylinder. The brake cylinder can only be replaced with an assembly, and cannot be repaired. So check the wear of brake pads and discs frequently.

Also with brake fluid.

Relatedly, if the brake fluid is not changed for a long time, it will cause the brake cylinder to rust. Therefore, it is necessary to change the brake fluid regularly, generally every three years or 60,000 kilometers.

Summary. Hello, dear, I'm honored to answer for you! <>

The reason why the brake cylinder is replaced and the heating is that the brake cylinder of the car is broken, and the brakes will be bad, or the tires will be "locked", resulting in the brake disc heating. The damage of the sub-cylinder is also related to the failure to replace the brake disc and brake pad in time, and when the brake disc and brake pad are worn to the limit, if they are continued to be used, the sub-cylinder may be damaged. The brake cylinder can only be replaced with an assembly, and cannot be repaired.

So check the wear of brake pads and discs frequently.

Why does the brake cylinder still heat up after it is replaced?

Hello. Wuling Hongguang S changed the wheel of the left pump to heat up.

Hello, dear, I'm honored to answer for you! <>

The reason why the brake cylinder is replaced is that the brake cylinder of the car is broken, and the brake brake will be bad, or the tire will be "locked", resulting in the brake disc heating. The damage of the sub-cylinder is also related to the failure to replace the brake disc brake leakage finger in time, and when the brake disc and brake pad are worn to the limit, if you continue to use it, it may cause damage to the sub-skin search and answer pump. The brake cylinder can only be replaced with an assembly, and cannot be repaired.

So check the wear of brake pads and discs frequently.

It is also related to the brake oil, if the brake fluid is not changed for a long time, it will lead to the rust of the brake shirt nano cylinder. Therefore, it is necessary to change the brake fluid regularly, or at all, every three years or 60,000 kilometers.

Wuling Hongguang S is a mini van, this early brother car wheelbase is 2720mm (mm), length, width and height are 4420mm (mm), 1685mm (milli Lu Sakura attack Song nuclear rice), 1755mm (mm). Wuling Hongguang S uses a total of two engines, one is a liter naturally aspirated engine, and the other is a liter naturally aspirated engine.

If the heat is excessive, the brake cylinder will not return, and there may be a problem with the piston of the cylinder. Brake disc heat, may be caused by brake lag caused by poor return of the brake trouser cylinder, if the vehicle's sliding distance is significantly shorter, there should be a phenomenon of brake lag, hail can go to the rental Li Fan 4S shop to lift the vehicle up to check the idling of the wheels and whether there is brake drag, if there is an abnormality, you need to check and test the return of the brake cylinder.

It is generally normal, because the brakes are all braked from the front:

1. The brakes have disc brakes, drum brakes and air brakes, and many older cars are front and rear drums. Many cars have disc brakes at the front and rear;

2. Because the disc brake has better heat dissipation than the drum brake, it is not easy to produce thermal decay in the high-speed braking state, so its high-speed braking effect is good;

3. However, when the low-speed cold brake is used, the braking effect is not as good as the drum brake. **More expensive than drum brakes. Therefore, many middle and high-end cars use full disc brakes, while ordinary cars use front disc and rear drum splitting, and relatively low-speed, and need large braking power for trucks and buses, still use drum brakes;

4. The drum brake is sealed, shaped like a drum, and there are many brake pots in China. It turns when driving. There are two arc-shaped or semi-circular brake shoes fixed in the drum brake;

5. When stepping on the brakes, the two brake shoes are stretched out under the action of the brake wheel cylinder, and the brake shoes are absolutely supported and rubbed against the inner wall of the brake drum to play the role of deceleration or stopping.
