It will work but you're not gonna have any control over the rear end when braking. Not to mention the front brakes will heat up faster and produce fade because they'll be picking up the slack... Not to mention slick conditions would be dangerous.
"Rear brakes help to reduce the stopping distance. Rear brakes help to preserve the life of the front brakes by sharing the workload. They tend to last longer than the front brakes because they don't endure the pressure that the front brakes do. The rear brake system helps control the car when it stops so that it doesn’t tilt or swerve in the back and veer off the road. The car is less likely to spin out or fishtail by having the balance of the rear brakes."
