What type of brakes are usually installed on the rear wheels of a vehicle?

Drum brakes are often installed on the rear wheels of many vehicles, especially in older models and some contemporary economy cars. One of the primary reasons for this choice is that drum brakes are typically more cost-effective to manufacture and install than disc brakes, making them a popular option for manufacturers looking to reduce production costs without significantly compromising safety.

In addition to their cost-effectiveness, drum brakes tend to provide adequate stopping power for the rear wheels, which generally bear less load than the front wheels during braking. This is because weight shifts forward when a car slows down, meaning the front brakes are subjected to more force. Drum brakes also provide effective braking in various conditions, including wet environments because the enclosed design helps prevent water and debris from interfering with performance.

While disc brakes are appreciated for their superior performance, especially in high-demand situations like heavy braking or racing scenarios, the rear wheels often leverage drum brakes for their reliability and cost factors. This combination of performance needs, design, and economic considerations explains why drum brakes are commonly found at the rear of many vehicles.
