do the rear brakes ever engage during normal braking?
The rear brakes engage every time you press the brake pedal.
then why do ppl press the brakes during a burn out?

Front brake bias, keeps the front of the car stopped while power from the rears is enough to overcome the brakes.

Exactly. While a majority of the braking force takes place in the front, the brakes engage front and rear every time you hit the brakes. You would not want only the front brakes to apply as it would cause very unstable and less effective braking. It is a different story on most motorcycles as they have a seperate hydraulic system (and lever/pedal) for the front and rear brakes so you can apply each independently.

Why would front only be very unstable?

Weight transfer from the back to the front. Move enough weight off the back and it will continue in a straight line when you turn.

Regardless of whether you're braking from the front only or front and rears, for the same deceleration, you get the same weight transfer.

You can easily manipulate oversteer/understeer on turn in by changing how much braking either set of wheels does.

Changing the brake bias will change the amount of available traction for steering for the front or rear tires. This is explained by looking at a circle of traction, not weight transfer.

Try drawing free body diagrams of a car with front wheel only and all wheel braking. It will show you the same weight transfer for the same deceleration... or you can just post another animated gif.
