1. The heat dissipation performance of disc brake is better than that of drum brake. When the brake is pressed continuously, it will not cause brake recession and brake failure.

2.刹车盘在受热之后尺寸的改变并不使踩刹车踏板的行程增加。

2. The change of the size of the brake disc after heating does not increase the stroke of stepping on the brake pedal.

3.盘式刹车系统的反应快速，可做高频率的刹车动作，因而较为符合ABS系统的需求。

3. The disc brake system has fast response and can brake with high frequency, so it meets the requirements of ABS system.

4.盘式刹车没有鼓式刹车的自动煞紧作用，因此左右车轮的刹车力量比较平均。

4. Disc brake has no automatic braking effect of drum brake, so the braking force of left and right wheels is average.

5.因刹车盘的排水性较佳，可以降低因为水或泥沙造成刹车不良的情形。

5. Due to the better drainage of the brake disc, it can reduce the situation of poor braking caused by water or sediment.

6.与鼓式刹车相比较下，盘式刹车的构造简单，且容易维修。小型搅拌车盘式刹车的缺点：

6. Compared with drum brake, disc brake has simple structure and easy maintenance. Disadvantages of disc brake of small mixer truck:

1.因为没有鼓式刹车的自动煞紧作用，使盘式刹车的刹车力较鼓式刹车为低。

1. Because there is no automatic braking effect of drum brake, the braking force of disc brake is lower than that of drum brake.

2.盘式刹车的刹车片与刹车盘之间的摩擦面积较鼓式刹车的小，使刹车的力量也比较小。

2. The friction area between the brake pad and the brake disc of the disc brake is smaller than that of the drum brake, which makes the braking force smaller.

3.为改善上述盘式刹车的缺点，因此需较大的踩踏力量或是油压。因而必须使用直径较大的刹车盘，或是提高刹车系统的油压，以提高刹车的力量。

3. In order to improve the disadvantages of the disc brake mentioned above, it is necessary to increase the pedal force or oil pressure. Therefore, it is necessary to use the brake disc with larger diameter, or increase the oil pressure of the brake system, so as to improve the braking force.

4. 手刹车装置不易安装，有些后轮使用盘式刹车的车型为此而加设一组鼓式刹车的手刹车机构。

4. The handbrake device is not easy to install. For some models with disc brakes on the rear wheels, a set of drum brake handbrake mechanism is added.

5.刹车片之磨损较大，致更换频率可能较高。

5. The wear of the brake pad is large, so the replacement frequency may be high.
