When the brake of the fully automatic self loading mixer is about to stop, the steering wheel always tilts to one side. This situation is actually what we usually call "bias braking". The main reason for the failure is that the left and right auxiliary pumps of the braking system of the automatic feeding mixer do not exert any force on the brake pads. During driving, due to the rapid rotation of the brake disc of the automatic feeding mixer, the difference between the uneven effect of the pump and the rapid friction is very small, which is difficult for us to feel.

启动混泥土自动上料搅拌车之前，需要花十多分钟的时间对汽车进行预热。自动上料搅拌车的制动系统是发动机提供的压力，该压力用于推动卡钳以夹紧制动盘，或推动制动盘与制动鼓摩擦。因此，如上所述的情况可能是压力传递传输管道中的压力损失，导致不能及时提供制动力。

It takes more than ten minutes to preheat the truck before starting the automatic concrete loading mixer. The braking system of the automatic charging mixer is the pressure provided by the engine, which is used to push the caliper to clamp the brake disc or push the brake disc against the brake drum. Therefore, the situation described above may be the pressure loss in the pressure transmission pipeline, resulting in the failure to provide braking force in time.

在这种情况下，请检查制动总泵的真空助力软管和混泥土自动上料搅拌车发动机的借口是否破裂或松动。

In this case, please check whether the vacuum booster hose of the brake master cylinder and the engine of the automatic concrete loading mixer are broken or loose.

自动上料搅拌车不会返回到制动位置。踩下制动踏板，踏板不会升起并且没有阻力。这种现象是制动器不返回。有必要确定是否缺少制动液，是否从制动缸，管路和接头处漏油，以及主缸和缸体零件是否损坏。

The automatic charging mixer will not return to the braking position. When the brake pedal is pressed, the pedal will not rise and there is no resistance. This phenomenon is that the brake does not return. It is necessary to determine whether there is a lack of brake fluid, whether there is oil leakage from the brake cylinder, pipelines and joints, and whether the master cylinder and cylinder block parts are damaged.
