What is the reason why the front wheel hub burns?

The problems of automobiles, such as tire burst and even spontaneous combustion caused by overheating of the hub, are particularly prominent in recent years. I don't know if you've ever heard of it. It's well known that if you step on the brakes, all the brake drums will get hot. The faster the car, the bigger the weight, the higher the heating of the brake. This is the principle of energy exchange. If the wheel is found to be unusually hot, the car Butler recommends that the following methods or timely inspection, troubleshooting. What is the reason why the front wheel hub burns?

Wheel hub (axle head) hot: bearing may be too tight or abnormal wear.

There are two possibilities for the front wheel hub to burn, one is the hub (axle head), and the other is the brake drum heating. The hub is the most innermost part of the brake drum, which is the axle head bearing the bearing after it is opened. Wheel hub (shaft head) blanching is generally caused by bearing assembly too tight or poor lubrication, excessive temperature will lead to the melting out of the grease inside to affect the braking effect, serious will burn the bearing.

Brake drum is hot: may not brake or drum phenomenon.

Brake drum is the thermometer you use to measure that commonly known as the "pot," as long as the brake, it will be hot, is the whole front wheel of the largest heat. And the brake drum temperature is related to the ambient temperature, speed, braking times, the weight of the car, road conditions, on a few feet brake, 100-200 degrees have, or even heavy clip downhill can reach more than 300 degrees.

If the brake drum is hot, you can lift the front wheel of the car and turn the tire to see if it rubs. Then turn the tire and step on the foot brake to see the brake return card.

If the tire is not flexible, indicating that there is interference in the drum, if the brake does not return or return slowly, that is the brake system is a problem, need to be repaired in time.
