How to detect the throttle brake?

Like the throttle, if the throttle feels particularly astringent and stuck when stepping on it, it is usually caused by dirty throttle or insufficient lubrication of the throttle cable. At this time you need to clean and lubricate the car. Secondly, when refueling, if you feel that the throttle is not as fast as usual or the engine is stuffy, then you should go to the maintenance station to check the spark plug, nozzle and throttle to see if it is necessary to replace the spark plug or clean the throttle and nozzle.

When you turn off the engine and press the brake pedal, the brake pedal must have enough hardness and height. When you press the brake pedal hard, the brake pedal should not feel slipping when it is still. If your foot feels slipping with the brake pedal, you should go to the maintenance station in time to check whether the brake system leaks oil.

Secondly, after the vehicle is started, there should be no phenomenon of forcibly stepping on the brake pedal, otherwise the brake system should be overhauled immediately. In addition, it is normal to step on the brakes after the vehicle starts and step on a few feet. When you release the brake pedal for a few minutes, you will step on the brake again, and it will be normal to step on a few feet. This shows that there is air in the pipeline of your brake system, so you should go to the maintenance station to deflate the brake system in time.
