Title: How to repair the drum brake of an electric car.
Electric vehicles are a very common means of transportation in our daily life, and it is loved by everyone for its convenient and environmentally friendly characteristics. However, various problems may occur during the use of electric vehicles, among which the drum brake is a more common one. So, how to repair the drum brake of an electric car if it doesn't work?Let's take a closer look at it.
First of all, we need to understand what a drum brake is. Drum brake is a type of braking system, and its main parts include brake drums, brake pads, and brake shoes. When the brake pedal is pressed, the brake pump will press the brake oil into the brake cylinder, pushing the brake shoe to move outward, make contact with the brake drum, and slow down or stop the vehicle through friction.
So, what are the reasons why the drum brakes of electric vehicles do not work?Generally speaking, the drum brake failure can be caused by the following reasons:
Insufficient brake fluid: Brake fluid is the medium that transmits the brake force, if the brake fluid is insufficient, it will not be able to generate enough pressure to push the brake shoe into contact with the brake drum, resulting in ineffective brakes.
Brake pad wear: The brake pad is the part that is in direct contact with the brake drum, if the brake pad is seriously worn, it will not be able to produce enough friction, resulting in ineffective brakes.
Brake shoe wear: The brake shoe is the part that is in contact with the brake drum, if the brake shoe is severely worn, it will not be able to generate enough friction, resulting in ineffective brakes.
Brake system oil leakage: If there is an oil leak in the brake system, the brake fluid will gradually decrease, resulting in ineffective brakes.
Once we understand why the drum brakes are not working, we can move on to repairs. There are several main ways to repair:
Replenish brake fluid: If the brakes are ineffective due to insufficient brake fluid, we only need to open the brake oil cap and replenish the appropriate amount of brake fluid.
Replace the brake pads: If the brakes are ineffective due to worn brake pads, we need to remove the worn brake pads and install new brake pads.
Replace the brake shoe: If the brakes are ineffective due to worn brake shoes, we need to remove the worn brake shoes and install new ones.
Fix the brake system leak: If the brakes are not working because of the brake system leakage, we need to find the oil leak and then seal it with special tools.
In the repair process, we need to pay attention to the fact that we must follow the prescribed methods and steps to avoid safety problems caused by improper operation. At the same time, after the repair is completed, it is necessary to carry out a test run to ensure the normal operation of the braking system.
In general, the problem of ineffective drum brakes of electric vehicles is not complicated, as long as we master the correct repair method, we can easily solve this problem. However, we must also understand that it is very important to carry out regular care and maintenance of electric vehicles, which can not only ensure the normal operation of electric vehicles, but also extend the service life of electric vehicles. Therefore, in the process of using electric vehicles, we must pay attention to regularly checking and maintaining the braking system of electric vehicles. Quality Author Certification Recruitment
