Solution:

Disk and drum brakes are used in vehicles according to conditions and requirements. Disk brakes dissipate heat quickly but are more costly, while drum brakes take more time to dissipate heat and are cheaper than disk brakes. You are tasked with deciding the type of brakes to be used in your 4-wheeled vehicle. According to the theory explained above and heat dissipation distribution in the front and rear wheels, which of the following will be the best and most economical option for your 4-wheeled vehicle?

Disk at the rear wheels and drum at the front wheels

Front with one disk and drum, rear with one disk and drum

Only disk brakes at all 4 wheels

Disk brakes at the front and drum brakes at the rear
