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.剎車盤在受熱之后尺寸的改變并不使踩剎車踏板的行程增加。

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

3.盤式剎車系統的反應快速，可做高頻率的剎車動作，因而較為符合ABS系統的需求。

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

4.盤式剎車沒有鼓式剎車的自動煞緊作用，因此左右車輪的剎車力量比較平均。

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

5.因剎車盤的排水性較佳，可以降低因為水或泥沙造成剎車不良的情形。

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

6.與鼓式剎車相比較下，盤式剎車的構造簡單，且容易維修。小型攪拌車盤式剎車的缺點：

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

1.因為沒有鼓式剎車的自動煞緊作用，使盤式剎車的剎車力較鼓式剎車為低。

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.盤式剎車的剎車片與剎車盤之間的摩擦面積較鼓式剎車的小，使剎車的力量也比較小。

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.為改善上述盤式剎車的缺點，因此需較大的踩踏力量或是油壓。因而必須使用直徑較大的剎車盤，或是提高剎車系統的油壓，以提高剎車的力量。

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. 手剎車裝置不易安裝，有些后輪使用盤式剎車的車型為此而加設一組鼓式剎車的手剎車機構。

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.剎車片之磨損較大，致更換頻率可能較高。

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