What if the wheel is locked?

1. Long-term storage: Generally, when there is water in the brake hub after washing the car or raining, pull the hand brake. If it is stored for a long time, it will lock up and the tire can be electrified;

2. The brake master cylinder cup is stuck: The solution to this problem is to clean the whole brake system and replace the brake master cylinder cup;

3. Brake cylinder does not return: it can be repaired by grinding and smearing butter. If the cylinder itself fails, it is likely to be replaced directly;

4. The brake lining is frozen due to freezing: melt the ice with hot water, or directly hit the brake drum twice with a blunt object such as a hammer;

5. The temperature is too high due to long-term braking, so that the brake pads cannot be separated by themselves: the brake pads need to be directly polished or replaced according to the situation. Million car purchase subsidy
