小型混凝土搅拌车踩刹车时发抖这种情况大多出现在老车身上，因为使用磨损，混凝土搅拌车刹车盘片表面平整度已经有一定程度的失准了。所以建议是视情况选择采用车床光盘工艺打磨，又或者更换刹车片(对于车龄较大的混凝土搅拌车)。

This paper introduces the importance of the brake system of the small concrete mixer. It trembles when the small concrete mixer steps on the brake. This kind of situation mostly occurs on the old car body. Because of the wear and tear, the surface flatness of the brake disc of the concrete mixer truck has lost its accuracy to a certain extent. Therefore, it is recommended to use the lathe disc technology for grinding or to replace the brake pad (for the concrete mixer truck with older vehicle age).

小型混凝土搅拌车刹车快停住的时候方向盘总会向一侧偏转，这种情况其实就是我们俗称的“偏刹”，故障原因主要是小型混凝土搅拌车刹车系统左右分泵对刹车片作用力不均匀导致的。而在行驶过程中由于小型混凝土搅拌车刹车盘转动速度快，分泵作用不均匀在快速摩擦时的差别是很小的，我们也很难感觉到。

The steering wheel always deflects to one side when the brake of a small concrete mixer stops. This situation is actually known as "partial brake". The main cause of the failure is the uneven force of the left and right sub pumps of the brake system on the brake pads. In the process of driving, due to the small concrete mixer brake disc rotation speed is fast, the wheel pump function is not uniform, the difference in rapid friction is very small, we are also very difficult to feel.

开动小型搅拌车前需要热车十多分钟才有刹车力，小型混凝土搅拌车刹车系统是由发动机提供压力推动卡钳夹住刹车盘(盘刹)，或者是推动刹车盘与刹车鼓发生摩擦(鼓刹)。所以像上述的状况，可能是提供压力的传输管道出现失压，导致无法及时提供刹车力。这种情况应检查刹车总泵的真空助力皮管和小型混凝土搅拌车发动机的借口处是否有龟裂或松脱的状况。

It takes more than ten minutes to warm up before starting the small mixer to get the brake force. The brake system of the small concrete mixer is driven by the engine to push the calipers to clamp the brake disc (disc brake), or to push the brake disc to rub with the brake drum (drum brake). Therefore, such as the above situation, it may be that the transmission pipeline providing pressure loses pressure, resulting in the failure to provide braking force in time. In this case, the vacuum booster hose of the brake master cylinder and the engine of the small concrete mixer should be checked for cracks or looseness.

混凝土搅拌车刹车不回位，踩刹车踏板，踏板不升高，无阻力，这种现象就是刹车不回位。需判断制动液是否缺失，制动分泵、管路及接头处是否漏油，总泵、分泵零部件是否损坏。

The concrete mixer brake does not return to its original position. If the brake pedal is stepped on, the pedal will not rise and there is no resistance. This phenomenon is that the brake does not return to its original position. It is necessary to judge whether the brake fluid is missing, whether there is oil leakage at the brake cylinder, pipeline and joint, and whether the parts of master cylinder and slave cylinder are damaged.
