The brake pads do not return, the fuel consumption is high, how to deal with it?

The braking system is an important part of the safe driving of the car, in which the normal return of the brake pads is crucial. When the brake pads do not return, it will not only directly affect the braking effect of the vehicle, but also may indirectly lead to an increase in fuel consumption. This article will deeply analyze the correlation between brake pad non-return and increased fuel consumption, and provide detailed treatment solutions to help car owners effectively solve problems, ensure driving safety and reduce fuel consumption.

First, the internal relationship between the brake pads not returning and the increase in fuel consumption.

The brake pad does not return, which means that after the brake is lifted, the brake pad fails to completely detach from the brake disc, and there is always a certain degree of contact, thereby increasing the driving resistance. This will lead to the following effects, indirectly contributing to higher fuel consumption:

1.Additional rolling resistance: The brake pads do not fully return to their positions, and the continuous contact with the brake disc creates additional rolling resistance, making the vehicle need more driving force to overcome this resistance while driving, resulting in higher fuel consumption.

2.Increased engine load: As the brake pads do not return, the engine will have to bear a greater load while providing the power demand at the same speed, which will further increase fuel consumption.

3.Heating of the brake system: The contact between the brake pads and the brake disc for a long time will overheat the brake system, affect its work efficiency, force the engine to continue to work at a higher load, and thus increase fuel consumption.

Second, the common reasons and inspection methods of brake pads not returning.

1.Brake cylinder failure: The brake cylinder is the main component that promotes the return of the brake pads, such as the internal piston return spring damage, jamming or oil leakage, which may cause the brake pads not to return. It can be preliminarily judged by checking the working status of the brake cylinder, the brake fluid level and whether there is oil leakage.

2.Brake return spring failure: The function of the brake return spring is to ensure that the brake pads can return to position in time after releasing the brake pedal. If the spring is broken or the elasticity is weakened, it should be replaced in time.

3.Improper adjustment of brake shoes: The gap between the brake shoes and the brake drum is not suitable, which may also cause the brake pads to not return completely. It is important to check and adjust the brake system regularly.

4.Brake line problems: Blocked or leaking brake lines that may affect the proper operation of the brake system, including the return of brake pads. These issues can be troubled by checking whether the brake line connections are secure, for leaks, as well as the quality and level of the brake fluid.

Third, the solution strategy of brake pads not returning.

1.Professional inspection and maintenance: When the problem of brake pads not returning is found, the vehicle should first be sent to a professional repair shop for a detailed inspection, find out the specific cause, and a professional technician will repair or replace the faulty parts.

2.Regular maintenance and maintenance: It is recommended that the owner regularly maintain the brake system in accordance with the provisions of the car manufacturer's maintenance manual, including changing the brake fluid, checking the wear of the brake pads and the working status of the brake cylinder, return spring and other components.

3.Develop good driving habits: Avoid the bad driving habit of half-pressing the brakes for a long time, which will not only accelerate the wear and tear of the brake pads, but also lead to the problem of the brake pads not returning. In the process of driving, reasonably control the distance between vehicles and minimize sudden braking, which is conducive to the normal operation of the braking system.

Brake pads not returning will not only reduce driving safety, but also indirectly lead to higher fuel consumption. In daily use, the owner should pay attention to the regular inspection and maintenance of the brake system, once the problem is found, should seek professional maintenance services in time, fundamentally solve the problem, ensure driving safety, reduce fuel consumption, and prolong the service life of the car.
