Why isn't the rear brake as big as the front one?

Due to dynamic weight shift during deceleration, there is significantly higher load on the front brakes. This can be as much as 70% front to 30% rear. Hence, the front brakes are typically the "bigger" brakes compared to the rear brakes. Take a look at motorcycle brake systems - there you can see the difference even better.
