What Is the Cost Difference Between Disc Brakes and Drum Brakes

The cost difference between disc brakes and drum brakes is mainly reflected in manufacturing costs, material costs, process costs, and maintenance costs. The following is a specific analysis of these differences:

1、 The Manufacturing Cost of Disc Brakes and Drum Brakes 

Disc brakes: Due to the relatively complex structure of disc brakes, high-precision machining and installation are required, resulting in relatively high manufacturing costs. In addition, disc brakes require additional accessories such as brake discs and brake calipers, which increase the manufacturing and procurement costs of these accessories.

Drum brakes: Drum brakes have a relatively simple structure with fewer components, and vehicle accessories such as shock absorbers can also be used to achieve braking effects, so their manufacturing cost is relatively low.

2、 The Material Cost of Disc Brakes and Drum Brakes  

Disc brakes: The brake discs, calipers, and other components used in disc brakes require high material requirements, usually requiring the use of high-performance metal materials, resulting in relatively high material costs.

Drum brakes: The materials used for drum brakes are mainly metal materials and drum shaped covers, which are relatively inexpensive and therefore have lower material costs.

3、 The Process Cost of Disc Brakes and Drum Brakes  

Disc brakes: The manufacturing process of disc brakes is relatively complex, requiring high-precision machining and installation to ensure braking effectiveness and safety. This high-precision machining and installation requirement increases the process cost.

Drum brakes: The manufacturing process of drum brakes is relatively simple, and the required machining and installation accuracy is also low, so the process cost is relatively low.

4、 The Maintenance Cost of Disc Brakes and Drum Brakes  

Disc brake: Although the initial cost of disc brake is relatively high, its maintenance cost is relatively low. Due to the relatively simple and compact structure of disc brakes, it is convenient to replace brake pads and other components, and the wear rate of brake pads is relatively slow, resulting in a lower frequency of replacement.

Drum brakes: The maintenance cost of drum brakes may be relatively high. Due to its relatively complex structure, it may be difficult to replace brake shoes and other components, and the wear rate of brake shoes may be faster, requiring more frequent replacement.

Overall cost difference

In summary, the cost difference between disc brakes and drum brakes is significant. Generally speaking, the cost of disc brakes is higher than that of drum brakes. This cost difference is mainly reflected in manufacturing costs, material costs, and process costs. However, in terms of maintenance costs, disc brakes may have a relative advantage.
