One brake disc is hot, the other has no temperature, what s the situation

If the temperature exceeds the normal range and is overheated and hot, there may be a problem with the parts, so don't be careless. It may also be that the brake cylinder is not well returned, and the brake pads and brake disc have been semi-combined, so the temperature of the brake disc is beyond the normal range.

When driving, be careful not to press the brakes for a long time, and try to shift the gear to low gear when going downhill, and let the engine control the speed. Do not use the brakes too much, otherwise the brake system will overheat and attenuate, which will eventually lead to the failure of the brake system.

It should be noted that when the brake disc is very hot, unless there are special circumstances, do not use water to cool it directly, so as not to cause deformation of the brake disc.

Hello friend, this type of malfunction described to you is very usually caused by the malfunction of the brake master cylinder. Carefully check the return of the brake master cylinder and the pressure of the brake line. Friends because the fault phenomenon is very obvious, according to the description of the fault state of the description to the general repair shop has its own inspection ideas and solutions, I hope the above two points of my inspection ideas can help you, if you have any questions, you can always pay attention to contact me.

Maybe the brake cylinder won't return, so you have to remove it and check it.

The temperature of a brake pad is too high, which may be caused by the locking of the brake pump, and it needs to be checked and maintained in time.

The brake cylinder is suspected of locking, and the incomplete separation of the brake cylinder causes the brake disc and the plate to rub all the time, and then friction generates heat.

Hello friends, in this case, it is recommended to check whether the brake cylinder is well returned.

Hello, the brake cylinder is not returned in time.

It is normal for the brake disc to be hot after driving for a while. This is because the brakes reduce the speed of the vehicle through friction between the brake caliper and the brake disc, which generates heat, so the brake disc heats up. If the car is driving normally and there is no braking operation, it is not normal for the brake disc to heat up.

The brake disc is a very important component in the braking system. There are disc brakes and drum brakes. The brake disc of the brake is a disc that also rotates when the car is moving.

Brake calipers are used to clamp the brake disc to generate braking force. Fixed with the brake disc that rotates oppositely, clamp the brake disc to slow down or stop when applying the brake.

1.If the car is driving normally and there is no braking operation, it is not normal for the brake disc to be hot. When the car is driving normally, there is no braking operation, and the heating of the brake disc indicates that there is still a certain friction between the brake disc and the brake pad, so the distance between the brake pad and the brake disc should be adjusted.

If the temperature is above the normal range, overheating and hot, there may be a problem with the part.

2.Under normal driving conditions, check the brake pads every 5000 kilometers, not only the remaining thickness, but also check the wear state of the brake pads, whether the wear degree on both sides is the same, whether the brake pads are free to return, etc. Any anomalies must be dealt with immediately.

When changing the brake pads, the brake cylinder must be pushed back using a special tool. Do not press back with other crowbars, it is easy to cause the lead screw of the brake caliper to bend and the brake pads to jam.

3.When replacing, the brake pads provided by the original parts should be replaced. Only in this way can the braking effect between the brake pads and the brake disc be optimal, with minimal wear.

After the brake pads are replaced, be sure to step on the brakes several times to eliminate the gap between the brake pads and the brake disc, resulting in the first foot not stepping on the brakes and prone to accidents.

When the vehicle is moving, try to avoid frequent braking. Otherwise, it will not only overheat the brake disc, but also break the brake pads, causing the brake to fail, bringing huge safety risks. Hot brake discs cannot be cooled directly with water, which will cause the brake discs to deform.

Some brake discs will find that there are many holes, which are actually used to dissipate heat. Overheating and burns can be avoided to a certain extent by using this type of brake disc.

If the owner controls the vehicle by braking suddenly, it is normal to drive for a few kilometers and the brake disc is hot, because the vehicle is rubbing against each other by the brake caliper and the brake disc to achieve the purpose of reducing the speed until the vehicle stops.

This situation is normal, we don't have to worry, as long as we reduce the speed, he won't get hot.

I don't think it's normal, probably because there's a problem with your car's brake discs, be sure to get some checks.

It is normal for Volkswagen Touran brake discs to run 20 kilometers and get hot, and the vehicle will heat up when the brake discs are driven for a long time. If there is a foreign body in the brake disc of the car, it will cause the brake disc to heat up abnormally when braking, which is an abnormal phenomenon, and the brake disc needs to be cleaned in time. Here's how to replace the brake disc:

1. Check the wear degree of the brake disc. In normal maintenance, the brake disc does not have to be replaced, according to the actual situation to judge whether to replace the brake disc, the brake disc has a notch of more than 3mm, the brake disc can be replaced;

2. Remove the front tires. If you want to replace the brake disc, you have to remove the two front wheel tires, and you can see that the round disc is the car brake disc;

3. Remove and fix the brake caliper screws. The brake disc is installed on the front wheel bearing, and there is a brake caliper on the outside to fix, remove the two 18 screws on the brake error, and remove the brake caliper, because there is an oil pipe connection on the brake caliper, and it should be put down slowly to prevent the oil pipe from breaking;

4. Remove the old brake disc. The old brake disc is installed on the front wheel bearing, and rust will be produced on the bearing and the brake disc, at this time, you can use a hammer to knock from behind the brake disc, and rotate the brake disc while knocking, so that all sides of the brake disc can be knocked on, and after several knocks, the old brake disc can be removed;

5. Install a new brake disc. After aligning the eyes of the new brake disc with the eyes on the bearing, gently tap the inside of the brake disc with a hammer to make it completely fixed on the bearing;

6. Install the brake caliper. Install the brake caliper in its original position, tighten the two fixing screws, and use the rotating bearing to check that there is an abnormal sound when it rotates.

It should be abnormal for the brake disc to be hot, the brake disc is hot depending on the situation, some cases are faulty, some situations are normal, stop the car and wait for the brake disc to cool down.

Under normal circumstances, the brake disc of the vehicle is very hot after a period of driving, which is caused by the following two reasons: first of all, the brake cylinder is not good to return to cause brake lag, and then there is the brake brake too often during the driving process.

The brake disc is hot caused by brake lag due to the poor return of the brake cylinder, and the brake cylinder needs to be repaired and replaced. If the brake disc is hot due to frequent use of the brake for a long time, you can stop and rest for a while, and wait for the brake disc to cool before leaving.

Normally, the brake disc and the brake pad also rub against each other during normal driving, so it is hot.

If you don't apply the brakes, it is not normal for the brake disc to be hot, and it may be caused by poor brake pad return. The gap between the disc brake pads and the brake disc is relatively small, and even if the brakes are not stepped on during normal driving, the brake disc may have a little temperature, but it will not get hot.

What's wrong with the car wheels being hot!

For veteran drivers (22 years of driving experience), it is a common problem that the wheels of the car are very hot. First, running long distances is more common. The reason is the heat generated by the friction of pressing the brakes.

Therefore, when running long distances, enter the service area to check whether the wheel rim is hot (fever is normal), if the temperature exceeds the normal range of overheating, hot, it may be: the gap between the brake pad and the hub is too small or bitten; Wheel bearings are damaged by lack of oil; Frequent braking applications; The tire pressure is too low. Second, instead of running long distances, it could be:

The gap between the brake pads and the wheel hub is too small or bitten, and the wheel bearings are often damaged due to lack of oil. The hot wheel hub is caused by friction of the brake pads and the heat conduction of the wheel hub when braking, which is a normal phenomenon.

However, it should be noted that do not step on the brakes for a long time, try to shift the gear to low gear when going downhill, and let the engine control the speed, but do not use the brakes too much, otherwise, the brakes will overheat and decay, which will eventually lead to brake failure.

In general, the brake disc of the vehicle is very hot after a period of driving, mainly due to the following two reasons:

1. If the return condition of the brake cylinder is not good, resulting in brake lag, in this case, it is necessary to stop driving and overhaul the brake cylinder of the vehicle;

2. Stepping on the brakes too often during driving, try to avoid stepping on the brakes frequently during the driving process, otherwise it is not only easy to overheat the brake disc and damage the brake disc, but also more likely to cause damage to the tires, starters and automatic transmissions of the car.

The braking effect becomes worse The weather temperature is high in summer Using the brake for a long time will heat up the braking system and affect your exercise safety It is recommended to use better brake pads.

Normal. Causes of brake disc heat:

1. Lack of maintenance and poor brake return.

2. The strength of the return spring of the brake cylinder is not enough.

3. Brake air leakage "automatic brake".

4. The brake debugging is not in place, resulting in overheating of the brake.

5. The brake drum is out of circle, and the brake wind pump is lost. These are also the causes of overheating of the brake discs.

After braking, it will heat up, if the heat is abnormal, it is estimated that it is time to replace the brake pads with new ......

Before you park normally, that brake will cause the brake disc to heat up, which is caused by the friction between the brake pads and the brake disc, unless you find a closed section of the road, and then drive up and let the car stop without using the brakes, and then you see if the temperature of the brake disc on all four wheels is the same?

The brake disc is very hot after the electric car is riding, what's going on, the master will help you analyze the reason.

Generally, the material of the more common brake disc is made of China's gray cast iron 250 standard, referred to as HT250, which is equivalent to the American G3000 standard;

2. The requirements of the three main elements of chemical composition are: C: Si: Mn:;

3. Mechanical property requirements: tensile strength: 21on mm2, hardness requirements: between 187 241, and some special or high-end models are also selected ceramic, high-carbon double aluminum alloy, etc.

Under normal circumstances, the brake disc will be very hot after driving and cannot be touched by hand. If you use a jack to prop up the tire, it is no problem to rotate flexibly.

If it is a long time to step on the brakes, of course it will be very hot, I think the brake disc material is very good, when the brakes are stepped on, the brakes will sound, the direction will deviate, if not, it is normal, rest assured to use.

Hello, the brake cylinder is not returned in time.
